Question

Given the functions k(x) = 5x − 8 and p(x) = x − 4, solve k[p(x)].

k[p(x)] = 5x − 12
k[p(x)] = 5x − 28
k[p(x)] = 5x2 − 12
k[p(x)] = 5x2 − 28

Answer 1

k(x) = 5x − 8 and p(x) = x − 4, solve k[p(x)]
"solve" is not the correct instruction here, should say "find"

k[p(x)] = k[x-4]
= 5(x-4) - 8
= .....

Answer 2

Given the functions k(x) = 5x − 8 and p(x) = x − 4, solve k[p(x)].

Answer 3

Given the functions k(x) = 5x − 8 and p(x) = x − 4, find k[p(x)].
