Unit 4 Review Algebra 2 Flashcards

1

Identify the equation that matches the parabola shown

y = 3.5x(x - 4)
y = 2x2 + 3x - 13
y = 3/2x(x + 4)
y = (x - 2)2 - 6

2

Factor: x² - 11x + 18

(x - 12)(x + 1)
(x - 6)(x - 3)
(x - 9)(x - 2)
(x + 11)(x - 1)

3

Simplify: 3√10*4√30

10√3
60√12
12√300
120√3

4

What is the absolute value of 3 - 5i?

√(9 + 25i2)
2√17
4
√34

5

Solve: 2(x + 3)² = 8

x = -5, 5
x = 5, 1
x = -1, -5
x = -5

6

Solve: 3x² - 16x = -5

x = 5
x = 5, x = -1/3
x = 1, x = 5/3
x = 15, x = 1

7

What is the axis of symmetry of 3x² - 12x +8?

-2
x = 1/8
x = 2
2

8

What is 4i*(1 - 3i)

4i - 12i
12 - 4i
-12 + 4i
12 + 4i

9

Solve: x² + 1 = 0

x = i, -i
No solution
x = 1, -1
x = i

10

What is the axis of symmetry of y = -2(x - 2)(x + 4)?

x = 1
x = 2
1
x = -1

11

What is the y-intercept of 3x² - 12x + 8?

(0, 8)
(0, -12)
(8, 0)
(-12, 0)

12

Where is Ms. Robinson from?

Houston
College Station
San Antonio
South Carolina

13

In order to simplify (4 + i)/(3 - i), we need to multiply by:

(3 - i)/(3 - i)
(3 + i)/(3 + i)
3 + i
3 - i

14

Solve: 16x² - 36 = 0

x = -3/2, 3/2
x = 3/2
x = √(36/16)
x = 6, -6

15

What is the axis of symmetry of y = 27(x + 2)² + 3?

x = -2
-2
2
x = 2
