Step-by-step explanation:
I can't draw here, and I did not use a graphing calculator. but I simulated this by using the first data point to test via estimates the 4 answer options, and the right answer is C.
x = 25, so x² = 625
7.821x² is then about 8×600 = 4800
0.936x is about 25
so, 4800 - 25 - 94 or -4800 + 25 - 94 are nowhere near 150 (the desired y value).
therefore, A and B are out.
0.008x² = 5
0.518x is about 25/2 = 12.5
so, 5 - 12.5 - 132 is a negative number and not 150.
therefore, D is out.
but 5 + 12.5 + 132 = 149.5, and that is close enough to 150.
so, C is correct.
