Graph Question

Answer 1

please write the equation

Answer 2

please you have to conjecture the equation below for your parabola:
\[y=ax ^{2}+bx+c\]
then you have to impose that your parabola passes through the three points indicated in your drawing, so you will find a system of three equations in three quantitties a, b and c. Soving that system you will find a, b and c, and after substitution you will get your equation

Answer 3

so don't i have to look at intercepts first

Answer 4

sorry I'm still confused..

Answer 5

ok! If I substitute the coordinates of point (0,12) into the equation above, I get:
\[12=a*(0)^{2}+b*0+c\]
so:
\[c=12\]
that's the value of the coefficient c.
Now, please try to substitute the coordinates of point (-1,0) into the above equation like I did before

Answer 6

oh okay
