Let f(x)=1/x and g(x)=x^2-7x what two numbers are not in the domain of f °g?

  x ∈ {0, 7} are not in the domain

Step-by-step explanation:

f(x) is undefined for x=0, so f(g(x)) will be undefined for g(x) = 0.

We are looking for the values of x that make g(x) = 0. They are the solutions to ...

  x^2 -7x = 0

  x(x -7) = 0

This product will be zero when either factor is zero, for ...

  x = 0 . . . or . . . x = 7

The domain of f(g(x)) excludes x=0 and x=7.

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.
