Question 15 options a y 101x2 066x 211 b y 053x2 468x

Question 15 options:

a) y = 1.01x2 + 0.66x + 2.11
b) y = 0.53x2 + 4.68x - 2.5
c) y = 1.01x2 - 0.66x + 2.11
d) y = 0.09 + 8.33x - 6.85

Solution

It seems that none of the equations displayed have values even near the ones desired. The values of y that we get by substituting x = 8 in the four equations are:

Similary, the value of y when x = 5 are:

Amongst these values, the results for (c) are the closest to each case. Therefore, the correct answer is (c).
