by Timothy Sullivan

Q.

The rate of change can be found using?

Differentiation
alternatives
Defferentiating
Q.

What is the average rate of change between x=3 and x=5 for $y=2x^{2\ }+4\$ ?

14

12

8

$\frac{2}{5}x^{5\ }-\frac{3}{2}x^2,\ 24$

Q.

Find the derivative and gradient at the pont x=2 $y=2x^4-3x\$

$8x^3-3,\ 61$

$8x^4-3x,\ 138$

$8x^3-3,\ 67$

$\frac{2}{5}x^{5\ }-\frac{3}{2}x^2,\ 24$

Q.

The function$f(x)=x^3\ –\ 6x^2+9x+15$is local maxima at

x = 1

x = 3

no point of maxima and minima

none of these

Q.

integrate ∫3x2 + 2x + 3 dx

x3 + x2 + 5x + c

0

x3 + x2 + 3x + c

x4 + x2 + 3x + c

Q.

For times t > 0, a particle moves on the x axis with its acceleration defined by a(t) = 6t – 2. If the velocity of the particle is -7 at t = 1, then at what time is the particle at rest?

t = 4

t = 1

t = 2

t = 4/3

Q.

How is our confidence level from 1-5?

1 = "Oh god help me that was complete nonsense and makes no sense"

2 = "some of that seemed familiar but I don't think I could do it"

3 = "i know this stuff but could do with some practice"

4 = "i can do this... I'm pretty sure at least"

5 = "step aside Mr. Tim! there's a new calculus expert in town"
