HEL The function g(t) = -16t2 + vt + h represents the height of an object, g, in feet above the ground in relation to the time, t, in seconds, since the object was thrown into the air with an initial velocity of v feet per second at an initial height of h feet.

A model rocket is launched off the ground at an initial velocity of 80 feet per second.
What domain makes sense for the function in this context?

A. all positive numbers

B. 0 ≤ t ≤ 5

C. all real numbers

D. 0 ≤ t ≤ 100

Step-by-step explanation:

The function is g(t) = -16t² + vt + h

At h = 0 and v = 80 we get the function:

We know g(t) can't be negative, then:

Correct option is B

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
