Let f(x) = x^2+4x. Evaluate the following with work. If you could explain how you got to your answer that\'d be great A) f(-4) B f(6)

Solution

Dear Student

Thank you for using Chegg !!

Given f(x) = x^2 + 4x

a) Now for f(-4) => x = -4

Implies we need to substitute x = -4 in the given expression of f(x)

f(-4) = (-4)^2 + 4(-4)

= 16 - 16

=0

b)

For f(6), x = 6

f(6) = x^2 + 4x

= 6^2 + 4(6)

= 36 + 24

= 60 Solution

Let f(x) = x^2+4x. Evaluate the following with work. If you could explain how you got to your answer that\'d be great A) f(-4) B f(6)SolutionDear Student Thank
