Question

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

Answer 1

When x = 8, f(x) = 44

f(8) = 44

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.

I hope you find my answer and explanation to be helpful. Happy studying.

Answer 2

44

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
