The value of y, when xa5isD The value of y2 when x.5is (Type integers or decimals.)

Explanation / Answer

Sol:

Given

y1 = 5.22x + 12.63

y2 = -0.054x^2 +6.058x +10.563

To find y1 and y2 when x=5

the value of y1 when x=5

y1 = 5.22*5 +12.63 = 38.73

the value of y2 when x=5

y2 = -0.054*5^2 + 6.058*5 + 10.563 = 39.503
