A function with am input of 6 has an output of 9. Which of the following could not be the function equation
y = (1.5)x
y = x + 3
y = 2x - 9
y = 15 - x

Answer 1

y=2x-9 could not be the function equation as it doesn't give output 9 to input 6

Further explanation:

In order to find the correct answer we will plug in the value of input and find output.

So,

y = (1.5)x

Putting x = 6

$y = 1.5(6)\\y = 9$

The function gives output of 9 at input 6

y = x + 3

Putting x = 6

$y = 6+3\\y = 9$

The function gives output of 9 at input 6

y = 2x - 9

Putting x =6

$y =2(6) -9\\y = 12-9\\y =3$

This function doesn't give the given output of 9 for the input 6 so this cannot be the function equation
