Identifying Functions, Solve Functions and Domain and Range

Dropdown

Range is all of the

values.If you need help look at slide #4

Dropdown

Domain is all of the

values.If you need help look at slide #4

Maximum: How high the range goes (TOP)

Minimum: How low the range goes (Bottom)

We look at the range (y-value) when reading this!!

Maximum is 800

*we are looking at the range (y-value)

Minimum is -9

*we are looking at the range (y-value)

Math Response

What is the maximum value of the function?

Type answer here

Deg^°

Rad

Math Response

What is the minimum value of the function?

Type answer here

Deg^°

Rad

Solve the function

This problem is asking us to replace all the X's (inputs) we see with (8) --> yes include the parenthese to avoid mistakes.

Using Desmos Calculator (above), the calculator will do all the hard work for us and pop out an answer.

Do not include the f(x)=

Math Response

Solve for the function.

$f\left(x\right)=2x^2+2$

when $f\left(-3\right)$ .

If you need help look at slide #7

Type answer here

Deg^°

Rad

Math Response

Solve for the function.

$g\left(x\right)=4x-10$

when $g\left(2\right)$ .

If you need help look at slide #7

Type answer here

Deg^°

Rad

Math Response

Solve for the function.

$h\left(x\right)=-13+x^2+x$

when $h\left(3\right)$ .

If you need help look at slide #7

Type answer here

Deg^°

Rad

Multiple Choice

Which graph represents a function. Whose range is the set of non-negative real numbers?

Multiple Choice

For which relation is $y$ NOT a function of $x$ ?

Use Desmos to graph a picture.

Multiple Choice

What is the domain of the graph?

How far left and right the graph goes on the x-axis.

$−5\le x\le7$

$−5\le x\le6$

$−5\le x\le4$

$−5\le x\le5$

Multiple Choice

What is the range of the graph?

How far up and down the graph goes on the y-axis.

$−4\le y\le9$

The y-values are -5, -2, 0, 2 and 5

The y-values are -4, 0, 9

$−5\le y\le4$

Multiple Choice

What is the domain of the graph?

How far left and right the graph goes on the x-axis.

$−7\le x\le7$

x values are:

{-7, -4, 0, 4, and 7}

x values are:

{-3, 0, and 4}

$−3\le x\le4$

Multiple Choice

What is the range of the graph?

How far up and down the graph goes on the y-axis.

$−4\le y\le5$

$−3\le y\le1$

$−3\le y\le6$

$−4\le y\le2$

Multiple Choice

What is the domain of the graph?

Draw an imaginary line to hit the x-axis

$−3\le x\le4$

The x-values are: {-2, -1, 1, 5 and 6}

The x-values are: {-5, -2, 6 and 7}

$−7\le x\le7$

Multiple Choice

What is the range of the graph?

Draw an imaginary line to hit the y-axis

$−7\le y\le7$

The y-values are: {-7, -4, -1, 3 and 7}

The y-values are: {-7, -6, -1, 3 and 4}

$−7\le y\le4$

Multiple Choice

What is the domain?

x = 2

−∞ < x < ∞

y = 2

none of these

Multiple Choice

What is the RANGE?

{-3, 3]

all real numbers

[-4, 5]

[-4, ∞)

Multiple Choice

What is the DOMAIN?

[0, ∞)

(-∞, 0)

All real numbers

{0, 1, 2, 3, 4,...}

Multiple Choice

What is the range of the function?

[-1, +∞)

(-1,1)

[1.5, +∞)

(-2, 2)

Multiple Choice

What is the range?

[-∞, +∞]

[-2, 2]

(-∞, ∞)

[0, 2]

Multiple Choice

Does the graph represent a function?
If you have an x value that has 2 "y" values it is NOT a function!

Yes, because the vertical line test shows there are no repeating input values

No, because the vertical line test shows there are repeating input values

Multiple Choice

Which graph does NOT pass the vertical line test?

Graph 1

Graph 2

Graph 3

Graph 4

Multiple Choice

Is the relation shown a function?

No, because the x-value 11 is paired with 5 and 8.

Yes, because each x-value has only one y-value paired with it.

Multiple Choice

Find the Range.

(-∞, +∞)

(0, 11)

[0, ∞)
