Answer:
[tex]f(5)=8[/tex]
Step-by-step explanation:
Given function: [tex]f(x)=x^2-3x-2[/tex]
To find [tex]f(5)[/tex], simply input [tex]x=5[/tex] into the function:
[tex]\begin{aligned}\implies f(5) & =5^2-3(5)-2\\& = 25-15-2\\& = 10-2\\& = 8\end{aligned}[/tex]
[tex]\huge\color{white}\boxed{\colorbox{Black}{♔︎Answer♔︎}}[/tex]
The value of f(5)
f(x) = x² - 3x - 2
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
The value of f(5) is 8.
