Question

If f(x) = x^2 + 3x - 5, find the value of
f (3)

Answer 1

Answer:13

Explanation:

in this kind of problems, you have to write 3 instead of every x, like this:

`x^(2) +3x-5--- > 3^(2) +3*3-5=9+9-5=13`

Answer 2

To find the value of f(3), we need to substitute 3 for x in the equation f(x) = x^2 + 3x - 5. Doing so, we get:

f(3) = 3^2 + 3 * 3 - 5
= 9 + 9 - 5
= 13

So, f(3) = 13
