Step-by-step explanation:
the given function: 
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 
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 
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 :
≥
Answer:
x = ± 
Step-by-step explanation:
Given
mx² = f ( isolate x² by dividing both sides by m )
x² =
( take the square root of both sides )
x = ± 
4 Trials of baking soda was conducted.
3.25 / 0.75 = 4.3 but you cant run a third of a trial so rounded down is 4.
I hope this helped :)
