If f(x) = 3x² + 1 and g(x) = 1 - x, what is the value of (f - g)(2)?
12, 14, 36, 38

Solution:

Given function f(x) = 3x² + 1 and g(x) = 1 - x

(f - g)(x)=f(x) -g(x)

(f - g)(x)= 3x² + 1- 1 + x

=3x² - x

We have to find (f - g)(2) so put x = 2

(f - g)(x)= 3x² + x

(f - g)(2) = 3(2)² + 2

=> (f - g)(2) = 14

If f(x) = 3x² + 1 and g(x) = 1 - x, what is the value of (f - g)(2)?

Summary: 

If f(x) = 3x² + 1 and g(x) = 1 - x,then the value of (f - g)(2) is 14.
