Consider the following. a = 15 (a) by reading values from the given graph of f, use five rectangles to find a lower estimate and an upper estimate for the area under the given graph of f from x = 0 to x = 30. (round your answers to one decimal place.) lower estimate ≈ 359.5 incorrect: your answer is incorrect. upper estimate ≈ 468 incorrect: your answer is incorrect. (b) find new estimates using ten rectangles in each case. (round your answers to one decimal place) lower estimate ≈ 384 incorrect: your answer is incorrect. upper estimate ≈ 43 incorrect: your answer is incorrect.

what are ur choices?

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
