1
Given the position function s(t) = -4.9t² + 36t + 120, when did the object hit the ground.
6.28sec
4.9sec
2.5sec
9.8sec
2
Find the tangent line at x = 3 of the function y = 3x² + 7x
y = 25x - 27
y = 27x - 25
y = 25x + 123
y = mx + b
3
Find the derivative of f(x) = 3x - Sin(4x)
f'(x) = -3cos(4x)
f'(x) = 3 - Cos(4x)
f'(x) = 3x - 4cos(4x)
f'(x) = 3 - 4cos(4x)
4
Find f'(x) of f(x) = 3cos(x)tan(x).
f'(x) = 3sinx
f'(x) = 3(sec x - sin x tan x)
f'(x) = 3(-cos (x) + sec2(x))
f'(x) = -3(sin x tan x + cos x)
5
Given the position function s(t) = -4.9t² + 36t + 120, What is the function velocity after 1sec
v(1) = 36 m/s
v(1) = -26.2m/s
v(1) = 45.8m/s
v(1) = 26.2m/s
6
Find dy/dx for y = 3e^{ln x}
y'=0
y' = 3/x
y' = 3
y'=3lnx

Find dy/dx of the following function. F(x) = Ln (3x² - 7).
6x/(3x2 - 7)ln(3x2 - 7)
2x/(x2 - 7)
6x/(3x2 - 7)
6xLn(3x2 - 7)
9
Find dy/dx for y = (3x - 7)¹²
y' = 0
y'=36(3x - 7)11
y'=12(3x - 7)11
y' = 36x
10
Find dy/dx for y = e^xLn x.
y' = ex + 1
y' = 1/x + ex
y' = ex(1/x + ln x)
y' = 0
11
Given the position function s(t) = -4.9t² + 36t + 120, what is the maximum height.
181ft
186ft
120
191ft
12
Find y' of the the function y = -3x⁴ + 5x³ - 4x² + 7.
y' = -12x3 + 15x2 - 8x 
y' = -3x3 + 5x2 - 4x
y = -5x
y' = -12x4 + 15x3 - 8x2
13
Find f'(x) for the function f(x) = tan^-1(3x²).
f'(x) = -6x/(1 + 9x4)
f'(x) = 6x/(√1+9x4)
f'(x) = 6x/(1 + 9x4)
f'(x) = 6xsec2(3x2)
14
find y' for 3x² + 5y² = xy
Are you kidding me
y' = (6x -y)/(x - 10y)
y' = 6x/(10y - 1)
y'=(y - 6x)/(10y - x)
