Question

If f(x)=2x^2-3x what is the value of f(5)

Answer 1

The answer is 35

Here's how I got my answer:

Step 1: Replace all x's with
`5`. Leaving us with
`2(5)^2-3(5)`

Step 2: Solve
`5^2`, which is
`25`. That leaves us with
`2(25)-3(5)`

Step 3: Solve
`2(25)`, which is
`50`. That leaves us with
`50-3(5)`

Step 4: Solve
`3(5)`, which is
`15`. That leaves us with
`50-15`

Step 5: Simplify 50-15 to get your answer, 35.

Answer 2

To find
`f(5)`, all you need to do is substitute 5 in for
`x` in
`f(x)`. This allows us to find our answer:

`f(5) = 2(5)^2 - 3(5)`

`f(5) = 50 - 15`

`f(5) = 35`

The answer is f(5) = 35.
