0
-3
• Question 6
180 seconds Q. What could be the equation for this graph?
y = -2x+ 1x + 3
y = (x - 2)(x + 1)(x + 3)
y = (x + 2)(x - 1)(x - 3)
y = -2x2 + 1x + 3
• Question 7
180 seconds Q. Which equation MOST LIKELY matches the graph?
y = x- x3 + 3x2 + 2
y = -x4 + x3 + 5x + 2
y = x3 - 2x2 + 1x + 3
y = -x3 - 2x2 + 1x + 3
• Question 8
180 seconds
Q. Which standard form function matches the factored form:
y = (x + 1)(x - 3)
y = x2 + x - 3
y = x - 2
y = x2 - 2x - 2
y = x2 - 2x - 3
• Question 9
300 seconds
Q. Which standard form function matches the factored form:
y = (x + 1)(x - 1)(x + 4)
y = x3 - x2 - 4x
y = x3 + 4x2 - x - 4
y = x3 - 4x2 + x + 4
y = x3 + x2 - x - 4
• Question 10
120 seconds Q. What is the degree of the function graphed here?
2
3
4
5
• Question 11
60 seconds Q. Classify the function:
cubic
quartic
linear
• Question 12
300 seconds Q. Find the standard form of the function graphed here:
y = x4 + 4
y = x4 - 3x3 + 4
y = x4 - 5x2 + 4
y = x4 - 5x3 + 4x
• Question 13
60 seconds Q. Find the factored form of the function graphed:
y = -(x + 1)(x - 1)(x - 2)
y= (x + 1)2(2 - x)
y = (-x + 1)2(x - 2)
y = -(x - 1)2(x + 2)
• Question 14
