Required answer: f(2) = -1

Detailed explanation:

To find f(-2), we will substitute -2 for x in the function:

`\bf{f(x)=-x^2+3}`

`\bf{f(-2)=-(-2)^2+3}`

`\bf{f(-2)=-4+3}`

`\bf{f(-2)=-1}`

Answer 2

F(-2) = 7

Explanation:

Finding a specific point on a function given the x position can be done by substituting x in the function for the given number, then solving said function. The value on the right side of the function is the y position.

For this specific function [F(x) = x² + 3], substitute x for -2.

F(-2) = (2)² + 3

Next, solve the equation.

F(-2) = 4 + 3

F(-2) = 7
