You Would End Up Doing:
A + (-1.3) = (-4.5)
(-4.5) - (-1.3) = (-4.5) + 1.3 = (-3.2)
A = (-3.2)

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 3x - 2

g(x) = x² - 5

<u>Step 2: Find g(f(2))</u>

f(2)

Substitute in <em>x</em>: f(2) = 3(2) - 2
Multiply: f(2) = 6 - 2
Subtract: f(2) = 4

g(f(2))

Substitute in <em>x</em>: g(4) = 4² - 5
Exponents: g(4) = 16 - 5
Subtract: g(4) = 11
