Using the function g(x) = -2x + 5, what would the input need to be for an output of -5? a.5 b.0 c.15 d.-5

A

Step-by-step explanation:

We are given the function g(x) = -2x +5

If we need an output of -5, then:

-5 = -2x + 5

-10 = -2x

x = 5

A

a. 5

Step-by-step explanation:

We can solve this by simply guessing and checking; plugging in each answer until we get -5.

a) -2(5) + 5

-10 + 5

-5

We can also set the function equal to -5 and solve for x.

-2x + 5 = -5

-2x = -10

x = 5

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values
