Question

If f(x)=2x^2+5 sqrt(x-2) complete the following statement
f(3)=

Answer 1

f(3) = 23

Explanation:

Put 3 where x is in the expression for f(x) and do the arithmetic.

... f(3) = 2·3^2 +5√(3-2)

... f(3) = 18 + 5 = 23

Answer 2

f(3)= 23

Explanation:

if
`f(x)=2x^2+5√(x-2)` complete the following statement

we need to find f(3). to find f(3) we replace x with 3 in f(x) equation

`f(x)=2x^2+5√(x-2)`

Plug in 3 for x

`f(3)=2(3)^2+5√(3-2)`

`f(3)=2(9)+5√(1)`

`f(3)= 18+5=23`

the value of f(3)= 23
