Answer: Option D
Explanation:
x = input
y = f(x) = output
Table D shows the input x = 2 pair up with the output y = f(x) = 0. But this curve does <u>not</u> cross the x axis. So we can conclude that table D is an incorrect model to represent this curve.
Answer:
-2x^2
Step-by-step explanation:
Simplify
x^-1 - 2x^2 - x^-1
becomes
-2x^2
Answer:
Option B: f(x) = 2x2 + 2x – 4
Step-by-step explanation:
2x^2 because you do (-4x^2)-x=(-6x^2) and solve for x to get 2x^2.
