Step-by-step explanation:

Step 1: Define

f(x) = -3x² - 7x

f(7) is x = 7

Step 2: Evaluate

The function has a value of f(7) = -196.

Step-by-step explanation:

In mathematics, we can define a value of a function if we are given a value for the unknown variable. In this case, our unknown variable is x.

Therefore, we see that our function is f(x) and we want to find f(7). This means we can change the value of x to be 7.

Firstly, we'll define our function:

Then, substitute f(7) for f(x).

Replace all of the values of x with 7.

Simplify using PEMDAS.

Distribute the -3 (multiply -3 and 49).

Simplify by subtracting the two values.

The final answer is f(7) = -196.

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

answer: y=0 if that is what u r looking for
