Answer 1

To find (f - g)(x), subtract g(x) from f(x), resulting in (f - g)(x) = x² + 10.

Step-by-step explanation:

To find (f - g)(x), we need to subtract g(x) from f(x). The function f(x) is given as 2x² + 3 and g(x) is given as x² - 7. So, (f - g)(x) = 2x² + 3 - (x² - 7). Simplifying the expression gives (f - g)(x) = x² + 10.
