Math Problem Statement

f(-2)

Solution

Let's evaluate the function f(x)=3x25x+1f(x) = 3x^2 - 5x + 1 at x=2x = -2.

Given: f(x)=3x25x+1f(x) = 3x^2 - 5x + 1

Substitute x=2x = -2:

f(2)=3(2)25(2)+1f(-2) = 3(-2)^2 - 5(-2) + 1

Now, calculate each term step by step:

  1. (2)2=4(-2)^2 = 4

  2. 3×4=123 \times 4 = 12

  3. 5×(2)=10-5 \times (-2) = 10

  4. Add these results together: 12+10+1=2312 + 10 + 1 = 23

So, the value of f(2)f(-2) is 2323.
