Answer:
Step-by-step explanation:
Notice that they are asking you to write the equation of the parabola in vertex form, that is using the coordinates of the vertex 
in the expression:
we can start by directly replacing the given vertex coordinates (-3, -3) in the expression, and then using the extra info on the point the parabola goes through in order to find the parameter 
:
So, now we can write the full expression for the parabola:
Answer:
2x^2+23.
Step-by-step explanation:
Combine like terms.
This expression simplified is 2x^2+23.
Answer:
The answer is D
Step-by-step explanation:
I just divided 9 by 20 and 1 by 4 then subtract 0.45-0.25 = 0.2
Answer:
x > -3
the third option
Step-by-step explanation:
the circle is not filled in so we can first rule out the 2nd and last option. then since the arrow is pointing towards the positive side we can say x is more than -3
