Answer:
x = 1.5
Step-by-step explanation:
Since the axis of symmetry is between the 2 x intercepts, we can find it by finding the average of the x-coordinates of the 2 points.
(-7 + 10) / 2
3/2
= 1.5
So, the axis of symmetry is at x = 1.5
Answer:
D)
Step-by-step explanation:
First we have to subtract 5 from both sides

Now, square both sides

x - 6 = 49
Now, add 6 to both sides
x - 6 +6 = 49 + 6
x = 55
Answer:
volume = 4/3 (pi x r^3)
Volume = 4/3 (pi x 15^3)
Volume = 4/3 (3.14 x 3375)
Volume = 14130 cubic cm

The parent function is 
That Parabola's equation is 
Step-by-step explanation:
I can't really explain much, but the top equation is a formula for <em>all </em>equations for a parabola. h and k are the x and y-values of the vertex. a is, well, a.
How did I find the equation of the parabola? Simple. Since the vertex is on the origin, h and k are 0. Also, because it intercepts (2,4) and (1,1), a=1.
