Use the function rule f(x)=x^2

Find f(2.5)__

6.25

Step-by-step explanation:

f(x)=x^2

f(2.5) = (2.5)^2

        =6.25

6.25

Step-by-step explanation: Notice that f is a function of x.

So we want to find f(2.5).

We find f(2.5) by plugging 2.5 in for x

everywhere that x appears in the function.

So we have f(2.5) = (2.5)².

(2.5)² is 6.25.

So our answer is 6.25.

it would open into a square depending on the type of envelope i’m not sure about the second part
