These all have variability.
Answer:
2x² +
x - 5
Step-by-step explanation:
(f + g)(x) = f(x) + g(x), thus
f(x) + g(x)
=
- 2 + 2x² + x - 3 ← collect like terms
= 2x² +
x - 5
Answer:
Yes.
Step-by-step explanation:
If the slope between successive points have the same slope then they will form a straight line.
Slope = ( 3.5- -1) / (-2 - -8) = 4.5/6 = 3/4
Slope = (12.5 - 3.5) / (10 - -2) = 9 / 12 = 3/4
Slope = (20-12.5)/(20-10) - 7.5/10 = 3/4 .
So the answer is yes.
