Answer:

The value of f(-1) in the given equation is -10.

Step-by-step explanation:

When we see f(-1), it means that -1 is represented as our value of x. So, knowing this information, we can plug this into our given equation.

f(-1) = -3(-1)² + 2(-1) - 5

Simplify the exponent on -1.

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

Multiply -3 by 1.

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

Multiply 2 by -1.

f(-1) = -3 - 2 - 5

Subtract 2 from -3.

f(-1) = -5 - 5

Subtract 5 from -5.

f(-1) = -10

The function defined by [tex]f (x) = -3x^2 + 2x - 5[/tex] when x = -1 is -10

Given the function [tex]f (x) = -3x^2 + 2x - 5[/tex]

To get f(-1), we will substitute x = -1 into the function to have:

[tex]f (-1) = -3(-1)^2 + 2(-1) - 5 \\f(-1)=-3-2-5\\f(-1) =-10[/tex]

Hence the function defined by [tex]f (x) = -3x^2 + 2x - 5[/tex] when x = -1 is -10
