Can I get some help finding the values of A, B and C please? Thanks!
A couple things to note:
We are given the coordinate
Also, we are told that the line is horizontal which means the slope is
So given this information the only choices are either c or d
To determine the coefficients of B and C I would take a guess and substitute the given values and evaluate.
The way to actually do this is that since you are given a point you can substitute that point as
So, if we guess choice C
So we validated that the coeffieicents for A,B,C are
Just so we know we are correct let's try choice d
Therefore c. is the only correct answer
The graph below shows the equation with the correct coefficient values crossing at the given point:
