Question

F(x)=x2-x find f (3)

Answer 1

`\huge \boxed{\sf{f(3)=6}}`

Explanation:

`\sf f(x)=x^2-x`

For f(3), the input or x value is 3.

`\sf f(3)=3^2-3`

Evaluate the expression.

`\sf f(3)=9-3`

`\sf f(3)=6`

Answer 2

f(3) =6

Explanation:

`f(x) =x^2 -x\\\\f(3) = ?\\\\f(3) = (3)^2 -3\\f(3) = 9-3\\f(3) =6`
