If f(x) = 4x + 8 and g(x) = (x+4,<br> what is (fºg)(12)?

svetlana [45]

Answer:

Step-by-step explanation:

$f(x) = 4x+8\\g(x) = x + 4\\\\1. f(g(x)) = 4(x+4) + 8\\2. f(g(x)) = 4x + 16 + 8\\3. f(g(x))=4x + 24\\\\4. f(g(12)) = 4(12) + 24\\5. f(g(12)) = 48 + 24 = 72\\$

To do these, you have to place the entire function inside the parent function's variables.

You are inputting the value of the function g(x) into f(x)

Paladinen [302]

$\text{Area of the triangle = 6 unit}^2$ Explanation:

The triangle is right angled.

The formula for area of the triangle:

$\begin{gathered} A\text{ = }\frac{1}{2}bh \\ \\ b\text{ = base} \\ h\text{ = height} \end{gathered}$

base = 3

height = 4
