The Chang family is on
their way home from a
cross-country road trip.
During the trip, the
function
D(t) = 2,280 - 60t can be
used to model their
distance, in miles, from
home after t hours of
driving.
Find D(15) and interpret
the meaning in the context
of the probieu.
If DC) = 1,200, find the
value of ĉ and interpret its
meaning in the context of
the problem.

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.
