Question

A function with an input of 4 has an output of 10. Which of the following could not be the function equation?

y = x + 6
y = 2 x + 3
y = 14 - x
y = (2.5) x

Answer 1

the second one

Explanation:

Answer 2

Its the second choice.

Explanation:

The correct functions will have y = 10 when x = 4.

1. y = x + 6 = 4 + 6 = 10 So this not the function we are looking.for.

2. y = 2*4 + 3 = 11. This is the one.

When x = 4, y = 11 for this function.
