Question

If f(x)=2x^2sqrt(x-2), complete the following statement f(6)

Answer 1

F(6) means that for every value of x in the function, you plug in a 6. So, 
f(6) = 2(6)^2 + 5*sqrt((6) - 2)

This equals 82.

Answer 2

F(x) = 2x^2 + 5sqrt (x - 2)....when x = 6
f(6) = 2(6^2) + 5 sqrt (6 - 2)
f(6) = 2(36) + 5 sqrt 4
f(6) = 72 + 5 * 2
f(6) = 72 + 10
f(6) = 82
