Answer:
It would be between -3 and 2
Step-by-step explanation:
cause -2.5 is greater than -3 and its less than 2

Answer:
A: 1(2x - 1) + 5(4x + 2)
B: Simplify above and divide by 0.5
C: (21 x 3) + (4 x 5 +2)
Step-by-step explanation:
In this question, you would be simplifying.
Simplify:
(-x³- x) + (6x² + 6x - 7)
-x³- x + 6x² + 6x - 7
-x³ + 6x² + 5x - 7
You can't simplify any further, so your answer would be:
-x³ + 6x² + 5x - 7
Answer:
-x^3 + 6x^2 + 5x - 7
Answer:
D
g(x) = 2 x²
Step-by-step explanation:
You are given a co-ordinate on g(x): (2,1). Plug this into the equaitons to see which one holds true.
A
g(x)=(0.5x)²?
2=(0.5(1))²?
2=0.25? NO
B
g(x)=(0.25x)²?
2=(0.25(1))²?
2=0.0625? NO
C
g(x)=0.5x²?
2=0.5(1²)?
2=0.5? NO
D
g(x)=2x²?
2=2(1²)?
2=2? YES
This could also be solved intuitively, since from the graph, you can see that the x values for g(x) are twice the x values for f(x), but the mathematical method above works too, and is useful if you find reading and assuming things from graphs difficult.
