Identifying Functions, Solve Functions and Domain and Range

Quiz Date

Due date for Edpuzzles and Khan Lessons.

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
