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
