Step-by-step explanation:
the given function: [tex]c(x) = 0.5x+70.[/tex]
Where C = cost (in dollars) and x is the number of miles you drive the truck.
when we compare the given function by slope- the intercept form y=mx+b, what we get is
Slope m = 0.5 whose fraction can be written as [tex]\frac{1}{2}[/tex]
And y-intercept b =70.
for us to be able to graph it, we need to plot y-intercept from 70 and then plot some more points by applying or increasing the points by [tex]\frac{1}{2}[/tex]
the shaded lines on the graph indicates the given function.
cost is at $70 for 0 number of miles. travelled.
Thus;
the Domain: x≥0 and Range : [tex]C(x)[/tex]≥[tex]70[/tex]
