For x = -2, evaluate f(g(x)) - f(0), given that: f(x) = 2x + 5 g(x) = 4x

-6

Step-by-step explanation:

Solve the expression with the given information.

They gave us what f(x) and g(x) are, we just need to evaluate them.

We also know that x = -2, so we would be plugging that to "x" in g(x).

Solve:

f(g(x)) - f(0)

Plug in the g(x) expression into "x" of the f(x) expression.

2(4x) + 5 - f(0)

Plug in -2 to x and solve.

2(4(-2)) + 5 - f(0)

2(-8) + 5 - f(0)

-16 + 5 - f(0)

-11 - f(0)

Evaluate f(0) by plugging in 0 to "x" in the f(x) expression.

-11 - 2(0) + 5

Simplify.

-11 + 5

-6

Your answer would be -6.
