PLEASE HELP I RLLY DONT KNOW WHAT TO DO For the function f(x) = 2x - 9, find the following
a. f(0)
b. f(2)
c. f(-3)
d. f(1/2)

a) f(0) = -9

b) f(2) = -5

c) f(-3) = -15

d) f(1/2)=-8

Step-by-step explanation:

We are given the function and we need to find the following:

a) f(0)

For finding f(0) put x =0 in the given function

So, we get f(0)=-9

b) f(2)

For finding f(2) put x =2 in the given function

So, we get f(2)=-5

c) f(-3)

For finding f(-3) put x =-3 in the given function

So, we get f(-3)=-15

d) f(1/2)

For finding f(1/2) put x =1/2 in the given function

So, we get f(1/2)=-8

b

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
