Math Problem Statement

f(x) = x^2 - 5 and g(x) = 6x - 2. Find f(g(2)).

Solution

The image provided contains a mathematical problem involving functions. Let's analyze and solve it step-by-step.

Given:

  1. f(x)=x25f(x) = x^2 - 5
  2. g(x)=6x2g(x) = 6x - 2
  3. We need to find f(g(2))f(g(2)).

Solution:

To find f(g(2))f(g(2)), we first need to compute g(2)g(2) and then substitute the result into the function f(x)f(x).

Step 1: Calculate g(2)g(2)

g(x)=6x2g(x) = 6x - 2

Substitute x=2x = 2:

g(2)=6(2)2=122=10g(2) = 6(2) - 2 = 12 - 2 = 10

Step 2: Calculate f(g(2))=f(10)f(g(2)) = f(10)

f(x)=x25f(x) = x^2 - 5

Substitute x=10x = 10:

f(10)=1025=1005=95f(10) = 10^2 - 5 = 100 - 5 = 95

Conclusion:

The value of f(g(2))f(g(2)) is 95.

Answer:

The correct answer is the orange box: 95.
