Question

Find g(x) if it is known that g(x+2)=4x−1

Answer 1

g(x)= 2g + 4x - 1

Explanation:

You focus on the parenthesis first, g multiplied by x equals gx and g multiplied by 2 equals 2g. Since you are trying to find g of x, you subtract 2g to isolate g of x

Answer 2

g(x) = 4x-9

Explanation:

Turn the left side into one that has (x+2) and is still equivalent. That would look like: g(x+2) = 4(x+2) - 9.

Since you are treating the (x+2) as a value, you can just substitute it with (x) because the outputs would be the same both ways.
