f’(x)=
The ball will reach 5m/s (16.404 ft/s) at 1.09822 seconds. The other two x values are not in the domain.

Part 3
f(x)=
-2x+4 -1 < x < 1-(x-1)^2+2 1 < x < 4-0.5|x-8|+6 4 < x < 12
Not continuous at x=4 because lim f(x)=4
And lim f(x)=7
x 4+
x 4-
They are not equal
Part 3
f(x)=
-2x+4 -1 < x < 1-(x-1)^2+2 1 < x < 4-0.5|x-8|-5 4 < x < 12
• Change function so there is a limit: move the absolute value equation/line down 11 units.Lim f(x) = -7 x 4Lim (x)= -7 x 4
+
-
• The limit does not exist at x = 4 because the left and right limits don’t equal each other.
Part 4
•Has a limit approaching infinity, as x approaches infinity.
F(x)= (3x^2+4x)/(2x+7)
Horizontal Asymptotes: None
Part 4
•Has a limit approaching 0, as x approaches infinity.
F(x)= (7x^2+3)/(2x^4+x)
Horizontal Asymptotes: y=0
Part 4
•Has a limit approaching a line which is not 0, as x approaches infinity.
F(x)= (3x^2+4x)/(4x^2)
Horizontal Asymptotes: y= 0.75 (Found using coefficients)
Part 4
•Has a limit approaching two separate lines as x approaches positive or negative infinity.
F(x)= (|2x|)/(3x)
Horizontal Asymptotes: y=2/3 and y= -2/3
(Found using coefficients)
