A rental car company charges $23.50 per day to rent a car and $0.05 for every mile driven. Matthew wants to rent a car, knowing that: He plans to drive 50 miles.
He has at most $120 to spend.

Use the drop-down menu below to write an inequality representing d, the total number of days Matthew can rent the car while staying within his budget.

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !

yes

step-by-step explanation:

lol

(a) x intercepts: -6 and 2

you can obtain these by solving the equation 0=x^2 +4x-12 using your favorite quadratic formula. but it is easy to verify -6 and 2 indeed satisfy this equation.

(b) y intercept: -12

this is obtained by setting x=0: 0^2+4*0-12 = -12

(c) the minimum value is: -16 (this is the vertex)

you can get the vertex by rewriting the equation into the form:

there is no global or local maximum as the function goes to infinity, so only in the limit sense: +infinity.
