The zeros of a parabola are negative 4 and 2 , and 6 comma 10 is a point on the graph. Which equation can be solved to determine the value of A in the equation of the parabola?
Answer
A
10 is equal to A open paren 6 minus 4 close paren open paren 6 plus 2 close paren
B
10 is equal to A open paren 6 plus 4 close paren open paren 6 minus 2 close paren
C
6 is equal to A open paren 10 minus 4 close paren open paren 10 plus 2 close paren
D
6 is equal to A open paren 10 plus 4 close paren open paren 10 minus 2 close paren
Explanation
A parabola with zeros at −4 and 2 can be written in factored form as y = A(x + 4)(x − 2). Substitute the point (6, 10), so x = 6 and y = 10: 10 = A(6 + 4)(6 − 2). This is choice D.
