Question

which function will have the greatest value at x equals 11 ?

Answer 1

Let's check each value of y at x=11

y = 7x

substitute x=11

y = 7(11) = 77

y = x² - 13x + 96

substitute x=11

y= 11² - 13(11) + 96 = 121 -143 + 96 = 74

y = 1.11^x

substitute x = 11

y = 1.11^11 =3.15

Hence, the function with the greatest value at x = 11 is y=7x
