-1x(6x - 8)
= -x(6x - 8)
= -x(6x) - x(-8)
= -6x^2 + 8x
If you would like to calculate - 5 * g - 6 for g = -2, you can do this using the following steps:
- 5 * g - 6 = - 5 * (- 2) - 6 = 10 - 6 = 4
g = -2
The correct result would be A. 4.
Laura is correct.
A function is a relation in which every x-value corresponds with no more than one y-value. In this problem, the x-value 1 has two different answers; this means it is not a function.
Additionally, if you graphed this, it would not pass the vertical line test.
