What are the two complex roots of x^2 + 2x + 2 it claims that the answer is -1+i and -1-i, however, after running this through the quadratic formula i got this: -1 + sqrt(2)i -1 - sqrt(2)i can someone me, the lesson i am on has been very poorly put together and i really want to understand this.

-1+i and -1-i are the actual answers

if we want to find the roots of the equation , we can use the quadratic formula. for quadratic equation of the form , , corresponds to a = 1, b = 2, c = 2; the solution to the equation is given by

since ,

  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).
