Which equation has the same solution as x2 + 16x + 9 = -3?

Step-by-step explanation:

x² + 16x + 9 = - 3

x² + 16x + 12 = 0

D = 16² - 4(1)(12) = 208

√D = 4√13

= ( - 16 - 4√13 ) ÷ 2 = - 8 - 2√13 ≈ - 15.21

= ( - 16 + 4√13 ) ÷ 2 = 2√13 - 8 ≈ - 0.79

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
