The graph of a function is a parabola that has a minimum at (-1,-2) and goes through the point (0,1).
what is the equation of the function in standard form?
substitute numerical values for a, b, and c.

Step-by-step explanation:

Since they give us the coordinates of the minimum of the parabola (the parabola's vertex), we start by writing the function in vertex form:

Now we use the fact that the point (0,1) is on the graph of the parabola, which means that when x=0, the value of the function (y) must be equal to 1.

We apply this to the expression we found above:

which gives us:    therefore,

Now we write the function using the value of the constant a we just found:

and next we find the square of the binomial (x+1) to express the function in standard form:

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
