For f(x) =1/x^2-3

find:

(a) f(3) (3 points)

(b) f(2+h) (3 points)

Step-by-step explanation:

Given

Required

Find f(3) and f(2 + h)

Solving f(3)

Substitute 3 for x in

Take LCM

Solving f(2 + h)

Substitute 2 + h for x in

Take LCM

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.

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.
