2ND QUARTER EXAMINATION


MATHEMATICS 9

Test I (Quadratic Inequalities)


Directions: Find the solution set and graph.

1) x2 – 10x + 16 < 0 2) y > x2 – 2x + 3 3) y > 2x2 - 8x + 7

Test II (Quadratic Function)


Directions: Write the indicated letter of the quadratic function in the form y = a(x-h)2 + k into the box that corresponds
to its equivalent general form y = ax2 + bx + c.

I y = (x-1)2 – 4 T y = (x - 1)2 -16

5 49
S y = 2(x + 4)2 - 8
F y = (x - 3)2 + 5

2 1 3
E y = (x - 3)2 – 2 M y = (x - 2)2 + 2

1
A y = 3(x + 2)2 - 2 U y = -2(x – 3)2 +1

N y = (x - 0)2 – 36 H y = 2(x + 1)2 – 2

DIALOG BOX:

y = x2 – x + 4

23
y = 3x2 + 12x + 2

y = x2 – 2x – 15

y = 2x2 + 4x

y = x2 – 2x -3

y = 2x2 + 5x -3

y = x2 – 6x + 14

y = -2x2 + 12x -17

y = x2 - 36
