3. a firework is shot into the air such that its height,
h, in metres, after t seconds can be modelled
by the function h(t) = -4.97 + 27t + 2.
a) copy and complete the table.
interval h? t? h/t?

hi, i just need trying to find out how to get the change in h and change in t. i’m kind of confused my teacher didn’t cover this topic and it’s in the hw questions

the answer for this question is 38

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.
