Question

Let f(x) = 3x – 4 and g(x) = 4 – 7x2.(fog)(2) =help (numbers)

Answer 1

Question:

Solution:

Consider the following functions:

$f(x)=3x-4$$g(x)=4-7x^2$

then:

$(f\circ g)(2)=f(g(2))=f(4-7(2)^2\text{ ) = f(-24)=3(-24)-4= -76}$

so that, we can conclude that the correct answer is:

$(f\circ g)(2)=\text{-76}$
