Question

If f(x)= 6x-4, what is f(x) when x=8

Answer 1

$f(x)=6x-4 \\ \\ f(8)=6 \cdot8-4=48-4= \boxed{44}$

Answer 2

Answer:

$f(8)= 44$

Step-by-step explanation:

We substitute the value of x = 8 where we see the variable x in the given function.

The funcion is:

$f(x)= 6x-4$

substituting x = 8

$f(8)= 6(8)-4$

solving operations, remembering that multiplications are resolved first than substractions.

$f(8)= 48-4$

$f(8)= 44$
