Solve the problem.Under certain conditions, the cost per mile C of operating a car is a function of the speed v (in mi/h) of the car, given by C = av2 + bv + c. If C = 25.25 ¢/mi for v = 5 mi/h, C = 26 ¢/mi for v = 20 mi/h, and 
for v = 35 mi/h, find C as a function of v.
A. C = 0.2v2 + 26v + 0.01 B. C = 0.01v2 -0.2v + 26 C. C = 26v2 - 0.01v + 0.2 D. C = 0.01v2 + 26v + 0.2
Sketch the graph of f(x). Determine the domain, range, and the equation of the horizontal asymptote of the function.f(x) = -e-x + 5
A. Domain: (-?, ?), range: (-?, 0)
Horizontal asymptote: y = 0
B. Domain: (-?, ?), range: (-?, 5)
Horizontal asymptote: y = 5
C. Domain: (-?, ?), range: (-?, 5)
Horizontal asymptote: y = 5
D. Domain: (-?, ?), range: (5, ?)
Horizontal asymptote: y = 5
