Operations with Function Notation- Problem Sets

#1) Find g(-3)

Guiding question: What is given input or output?

Substitute -3 into g(x) = x^2 +5

Use parenthesis around -3

#2) Find f(-2) + g(3)

Guiding questions:

What information is given?

Look at page 5 in your packet.

Set up 3 steps to find your final answer.

#3) Find g(4) - f(-2)

Guiding questions:

refer back to previous slide

#4 find 3[g(2)]

Guiding questions:

What do you need to find first?

Multiply 3 times g(2)

1.)

3.) Find the product of h(-4) and p(5.2)

Guiding Questions:

What does product mean?

Look at the example 1d on page 15

4.) p(3) - 3[h(2)]

Guiding Questions:

Look at #4 from problem set 1. If you got that wrong, try it again, call a friend, find a video, email me.

#1) If f(x)=70, determine the value of x.

Guiding Questions:

What is given, input or output?

Find a similar problem.

2.) Find the value of x for which f(x)=g(x).

Guiding Questions:

This looks more challenging than it really is. TRANSFER your skills.

Do you know what f(x) is equal to?

Do you know what g(x) is equal to?

Set them equal to each other and solve.
