Answer:
F(x) = 1/x^2
Step-by-step explanation:
F(x) = 1/x^2 is
y = 1/x^2
graph goes up to 10 each side
plug in 1,2,3,4,5,6,7,8,9,10 for x and see what y looks like
when x is 1,2,3,4,5,6,7,8,9,10
y is 1,1/4,1/9,etc
(a)
if then and if x<0 then
(b)
That is straightforward from what you showed on theorem 3.25
(c)
Following the same ideas from (a) x>a or -x > a.
Remember how we define the absolute value of a number.
In general
Therefore if you have two cases, if then and if x<0 then
Jim can type 315 words in 3.5 minutes.
90 x 3.5
A=342 ft^2 (dark section)
A = 108 ft^2 (light section)
18 x 25 = 450
9 x 12 = 108
450-108= 342
i think the answer is -3/4
