Question

Which input value produces the same output value for

the two functions on the graph?

X = -1
X = 0
X = 3
X = 4

Answer 1

D: x = 4

Explanation:

just took the test :-)

Answer 2

x = 4

Explanation:

The input values are the x-values represented in the graph while the output values are the y-values.

The x-coordinate of the point at which the line of the two functions intersect, f(x) and g(x), is the input values that produces the same output values for both functions.

Thus:

For f(x), when x = 4, y = 3. That is f(4) = 3.

Also, for g(x), when x = 4, y = 3. That is g(4) = 3.

Therefore, the input values that produces the same output values for both functions is x = 4.
