The height of a rocket at different times after it was fired is shown in the table.
time- 0.00 | 1.00 | 2.00 | 3.00 | 4.00 | 5.00 |
height- 50.0 | 65.1 | 70.4 | 65.9 | 51.5 | 27.5 |
find an equation for the data shown.
what is the maximum height?
how long will it stay in the air?
20 points to whoever answers all three.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
