Answer:
D : { -3, 3, 12}
Step-by-step explanation:
I would suggest substituting the range for the function and solving for x like so.
i.e -6 = 1x-3, -6 + 3 = 1x -3 + 3, -3 = x, <u>x = </u><u>-</u><u>3</u><u>.</u>
0 = 1x - 3, 0 + 3 = 1x - 3 + 3, 3 = x, <u>x = 3</u><u>.</u>
9 = 1x - 3, 9 + 3 = 1x -3 + 3, 12 = x, <u>x = 12</u>
88cm
calculation:
circumference = 2 x pi x radius
2 x pi x 14 = 87.9cm
if you round this you get 88cm circumference
Answer: C. rationalizing the denominator
Rationalizing the denominator is a useful step to simplify expressions where there are square roots in the denominator. It doesn't apply to actually solving a quadratic. On the other hand, the quadratic formula can solve quadratics. The same applies for choices B and D as well.
