Question

F(x)=18x+11, find f(5)

Answer 1

`\boxed {\tt f(5)=101}`

Explanation:

We are given the function:

`f(x)=18x+11`

and asked to find f(5). Therefore, we must substitute 5 in for each
`x`.

`f(5)=18(5)+11`

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

Multiply 18 and 5.

`f(5)=90+11`

Add 90 and 11.

`f(5)=101`

f(5) is equal to 101.
