Given:

f(x) = 3x^2 + 2x - 1

Find the vertex.

 (-1/3, 0) (-1/3, -4/3) (1/3, 0) (1/3, 4/3)

Question 2

Given:

f(x) = 3x^2 + 2x - 1

Find the y-intercept.

 (-1, 0) (0, 1) (0, -1) (1/3, 0)

Question 3

Find all solutions for x : l 3x-4 l= 20

 x = 8 or x = 16/3 x = -8 or x = -16/3 x = 8 or x = -16/3 x = 8

Question 4

Determine the domain of the function: h(x)=x-3/(x-2)(x+1)

 All Real numbers excluding x=2 and x=-1 All Real numbers excluding x=3, x=2 and x=-1 All Real numbers excluding x=0, x=2 and x=-1 All Real numbers excluding x=-2 and x=1

Question 5

Write the equation of the line with slope -2/3 and y-intercept 3. Write the answer in slope-intercept form.

 y = (2/3)x - 3 y = 3x - 2/3 y = (-2/3)x + 3 y = -3x + 2/3

Question 6

Find the equation of the line whose slope is 5 and which passes through the point (1, 2).

 y = 5x - 9 y = 5x - 3 y = 2x + 5 y = 5x + 2

Question 7

Solve the system of equations :

6x-y=3

5x+3y=-9

 can't be done (0, -3) (0, 3) (0, 0)

Question 8

Given:

f(x) = 3x² + x - 1

g(x) = x² - 2x + 3

Find: (f - g)(x)

 2x² + 3x - 4 4x² - x + 2 2x² - x - 2 3x² + 2x - 3

Question 9

Given:

f(x) = 3x + 2

g(x) = 4x - 3

Find:

(fog) (x)=

 12x + 5 12x² - x - 6 12x - 7 12x - 1
