Using the function g(x) = 0.4x - 1.8, what would the input need to be for an output of 4.6?

LenaWriter [7]

g(x) = 0.4x - 1.8

Since the output, or g(x), is 4.6, substitute that number in for g(x).

4.6 = 0.4x - 1.8

Add 1.8 to both sides of the equation.

4.6 + 1.8 = 0.4x - 1.8 + 1.8

6.4 = 0.4x

Now, divide 6.4 by 0.4.

The answer is x = 16. The output is also x.
