Question

Fill in the table for y= 2z² - 6.

Answer 1

(0,-6)

(2,2)

(4, 24)

Explanation:

y = 2
`x^(2)` - 6

y = 2(
`0^(2)`) - 6

y = 2(0) - 6

y = 0 _ 6

y = -6

y = 2
`x^(2)` - 6

y = 2(
`2^(2)`) - 6

y = 2(4) - 6

y = 8 - 6

y = 2

y = 2
`x^(2)` - 6

y = 2(
`4^(2)`) - 6

y = 2(16) - 6

y = 32 - 6

y = 24

Answer 2

1. y=-6
2. y=2
3. y=26
