5. last year, dan and paula regularly invested $25/week in a mutual fund account. this
year, they increased their weekly investment by 10 percent. what amount did they invest
in the account over the past two years? (hint: there are 52 weeks in a year.)

49/6 is going to equal 8 1/6

what do you mean

have a great day

1/4 is the asnwer cuz 5/20 is the faction

(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.
