Question

The function f is defined on the real numbers by f(x) = 2 + x - x^2. What is the value of f(-3)?

A) 7
B) 14
C) -11
D) 11

Answer 1

The value of the function f(x) at x = -3 is calculated by substituting -3 into the equation, resulting in -10, which doesn't match any of the provided answer choices.

Step-by-step explanation:

To find the value of the function f(x) = 2 + x - x^2 at x = -3, substitute -3 for x in the function:

f(-3) = 2 + (-3) - (-3)^2

= 2 - 3 - 9

= -1 - 9

= -10

Therefore, the value of f(-3) is -10, which is not listed in the options provided. There might be a mistake in the question or the options given.
