the following function models the distance in miles H hours

the following function models the distance in miles. H (hours) of traveling by car. d(h)=350-65h. State the vertical intercept of the model. Write it as an ordered pair. Also, find the horizontal intercept of the model.

Solution

a)

d(h)=350-65h

for vertical intercept, put h=0

d = 350-0 = 350

Answer: (0,350)

b)

for horizontal intercept, put d(h) = 0

350 – 65h =0

h = 13/70

Answer: (13/70 , 0)
