Question

For which value of X is the row in the table of values incorrect? The function is the quadratic function Y=3/4x^2

Answer 1

x = 2

Explanation:

check by substituting each given value of x into the function

x = 0 ⇒ y =
`(3)/(4)` × 0² = 0

hence (0, 0) is correct

x = 2 ⇒ y =
`(3)/(4)` × 4 = 3

hence (2, 4 ) is incorrect

x = 3 ⇒ y =
`(3)/(4)` × 9 = 6
`(3)/(4)`

hence (3, 6
`(3)/(4)`) is correct

x = 5 ⇒ y =
`(3)/(4)` × 25 = 18
`(3)/(4)`

hence (5, 18
`(3)/(4)`) is correct
