Question

What is w(4) for the function w(x)=3x+7

a)19
b)14
c)33

Answer 1

If w(x)=3x+7 , then w(cow)=3cows+7 , and w(mouse)=3mice+7 and w(4)=3fours +7.

This last one is the one you have to work with.

w(4) = 3 fours + 7

w(4) = 3(4) + 7

w(4) = (12) + 7

w(4) = 19

Answer 2

the answer for w(4)=3x+7 is a)19
