When using a quadratic equation in the form y = ax2 + bx + c to model the height of a projectile (y) over time (x), which of the following is always represented by the constant term?
the initial height of the projectile
the initial velocity of the projectile
the time at which the projectile hits the ground
the maximum height of the projectile
its not b , i already

The general form of a quadratic equation is .

We want to know what is meant by the constant term, c.

If we let x=0, we have y=c. What does this mean?

y is the height and x is time, so y=c at x=0 means at time 0, the height of projectile is c, or, the initial height of the projectile is c.

c, thus, is the initial height.

ANSWER: "the initial height of the projectile"

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
