I don’t understand how to do this please someone help ASAP

−(1−2/3x+11/15x^4)

Step one: Move the negative in front of the fraction.
−(15x^4−10x^3+11)/15x^4
Step two: Split the fraction into two fractions.
−(15x^4−10x^3 /15x^4 +11/15x^4)
Step three: split the fractions again
−(15x^4/15x^4 −10x^3 /15x^4 +11/15x^4)
Step four: Cancel the common factor of
15.
−(x^4/x^4 −10x^3/15x^4 +11/15x^4)
Step five: Cancel the common factor of x^4
−(1−10x^3/15x^4+11/15x^4)
Step six: Cancel the common factor of −10 and 15
−(1−2x^3/3x^4+11/15x^4)
Step seven: Cancel the common factor of x^3 and x^4.
−(1−2/3x+11/15x^4)
Step eight: move the negative in front of the fraction

This took me a while to type dude

  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.

f(-2) = -3f(1) = 6 . . . estimated from f(x) = (x+2)^2-3, which matches points on the graph (-1,-2) and (0, 1)

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

the table tells us

g(-2) = 1g(1) = 31

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).
