Question

Consider the functions f(x) = 4x^2 and g(x) = 5(x + 7). Find f[g(−5)]"

Answer 1

this is my new question. Last 1

Answer 2

uh, this is pretty simple and ill solve it , but i want you to try it first

Answer 3

Then ill post my solution

Answer 4

Answer 5

wait dont tell me the answer let me try first

Answer 6

100[-60(-5)] then solve this?

Answer 7

would the answer be 30000

Answer 8

uh, nope... solve g(-5)

Answer 9

Put (-5) into g(x), 5(x+7)

Answer 10

400?

Answer 11

Very Good

Answer 12

Okay.. first step is to calculate the function in the bracket

that is g(-5); = 5(-5+7) = 10

then sub the answer into the f(x); = 4(10)^2 = 400
