The figure above shows the graph of f ', the derivative of a twice-differentiable function f, on the interval [–3, 4]. Answer the following questions based on the graph of f '. a) Find all x-coordinates at which f has a relative minimum. Justify your answer.
b) On what open intervals contained in [–3, 4] is the graph of f both concave up and decreasing? Justify your answer.
c) Find the x-coordinates of all points of inflection on the graph of f.
d) What is the average rate of change of f ' between x = 0 and x = 3?

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
