Question

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

Answer 1

Answer:

44

Step-by-step explanation:

Step 1:

f ( x ) = 6x - 4         Function

Step 2:

f ( x ) = 6 ( 8 ) - 4       Substitute

Step 3:

f ( x ) = 48 - 4       Multiply

Answer:

f ( x ) = 44     Subtract

Answer 2

Answer:

When x = 8, f(x) = 44

f(8) = 44

Step-by-step explanation:

So we are given that f(x) = 6x - 4 and we are asked to find what f(x) is if x = 8. To find this, we have to plug in 8 for x into the given equation and solve.

f(x) = 6(8) - 4 = 48 - 4 = 44

So when x = 8, f(x) = 44. We can shorten this to be f(8) = 44, as it shows that we are setting x = 8 in the equation.
