Answer 1

`\huge\color{white}\boxed{\colorbox{Black}{♔︎Answer♔︎}}`

To find :-

The value of f(5)

Given :-

f(x) = x² - 3x - 2

Solution :-

f(x) = x² - 3x - 2

we will put the value of x as 5

so that to find f(5).

f(5) = (5)² - 3×5 - 2

f(5) = 25 - 15 - 2

f(5) = 8

Result :-

The value of f(5) is 8.

Answer 2

`f(5)=8`

Explanation:

Given function:
`f(x)=x^2-3x-2`

To find
`f(5)`, simply input
`x=5` into the function:

`\begin{aligned}\implies f(5) & =5^2-3(5)-2\\& = 25-15-2\\& = 10-2\\& = 8\end{aligned}`
