Question 3
describe the number and nature of the roots of the function. (you may want to view the graph of the function to
you identify the nature of the roots)
f(x) = 25 – 3x3 - 2
3 real and 2 non-real
3 real and 5 non-real
5 real and o non-real
oreal and 5 non-real

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

the answer is a. q=6,r=6√2

step-by-step explanation:

the answer is: -22 also a
