It takes a motorboat twice as much to cover the distance going upstream as it takes it to cover the same distance going downstream. Write the ratio of the speed of the boat in still water to the speed of the current. PLS HELLL THIS IS DUE IN 3 MINS

i would think "anyone would want the best for their child" is correct

i think this is a open ended question but i agree with other guy who said you should ask it at english section

(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.
