What is the equation of the quadratic function represented by this table?

MA_775_DIABLO [31]

Answer:

Step-by-step explanation:

I used logic and took the easy way around this as opposed to the long, drawn-out algebraic way. I noticed right off that at x = -3 and x = -1 the y values were the same. In the middle of those two x-values is -2, which is the vertex of the parabola with coordinates (-2, 4). That's the h and k in the formula I'm going to use. Then I picked a point from the table to use as my x and y in the formula I'm going to use. I chose (0, 3) because it's easy. The formula for a quadratic is

$y=a(x-h)^2+k$

and I have everything I need to solve for a. Filling in my h, k, x, and y:

$3=a(0-(-2))^2+4$ and

$3=a(2)^2+4$ and

-1 = 4a so

$a=-\frac{1}{4}$

In work/vertex form the equation for the quadratic is

$y=-\frac{1}{4}(x+2)^2+4$

In standard form it's:

$y=-\frac{1}{4}x^2-x+3$

Two hot air balloons are traveling along the same path away from a town, beginning from different locations at the same time. He

Answer:

D. Henry's started farther, went faster

Step-by-step explanation:

Henry's balloon traveled 18 additional miles (from 30 to 48) in 2 hours, so had a speed of 18mi/(2h) = 9 mi/h. The equation for his position could be ...

y = 9x +30 . . . . . 9 is the rate of change; 30 is the initial value

Comparing this to Tasha's position function, we see her balloon started 20 miles from town and traveled 8 miles per hour.

Henry started farther from town and traveled faster.
