Question

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

Answer 1

44

Explanation:

when you plug x into the equation, you get

6(8)-4, which simplifies to 48-4. After this, you get 44.

Answer 2

Answer:f(x) = 8x + -4

Multiply f * x

fx = 8x + -4

Reorder the terms:

fx = -4 + 8x

Solving

fx = -4 + 8x

Solving for variable 'f'.

Move all terms containing f to the left, all other terms to the right.

Divide each side by 'x'.

f = -4x-1 + 8

Simplifying

f = -4x-1 + 8

Reorder the terms:

f = 8 + -4x-1
