Question

If f(x) = x2-x+3, what would the function look like once you substitute in a -3 to find

f(-3)?

Can someone answer really quick please .

Answer 1

havent learned that yet

Explanation:

Answer 2

`\huge \boxed{f( - 3) = 15}`

Explanation:

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

To find f(-3), substitute the value of x that's - 3 into f(x). That is for every x in f (x) , replace it with - 3

We have

`f( - 3) = ({ - 3})^(2) - ( - 3) + 3 \\ = 9 + 3 + 3 \\ = 9 + 6 \: \: \: \: \: \: \:`

We have the final answer as

`f( - 3) = 15`

Hope this helps you
