HEY GUYS, I JUST TOOK THE TEST AND THESE ARE THE RIGHT ANSWERS. QUESTION 1 - Which graph represents the function of f(x) = the quantity of 4 x squared minus 4 x minus 8, all over 2 x plus 2?

graph of 2 x minus 4, with discontinuity at negative 1, negative 6 (CORRECT OPTION)

graph of 2 x minus 4, with discontinuity at 1, negative 2

graph of 2 x plus 2, with discontinuity at negative 1, 0

graph of 2 x plus 2, with discontinuity at 1, 4

QUESTION 2 - What is the discontinuity and zero of the function f(x) = the quantity of 2 x squared plus 5 x minus 12, all over x plus 4?

Discontinuity at (−4, −11), zero at (3/2 , 0) (CORRECT OPTION)

Discontinuity at (−4, −11), zero at (-3/2 , 0)

Discontinuity at (4, 5), zero at ( 3/2 , 0)

Discontinuity at (4, 5), zero at (-3/2 , 0)

QUESTION 3 - What are the zero(s) of the function f(x) = the quantity of 4 x squared minus 36 x, all over x minus 9?

x = −9

x = 0 (CORRECT OPTION)

x = 9

x = 0 and x = 9

QUESTION 4 - What is the discontinuity of the function f(x) = the quantity of x squared minus 4 x minus 12, all over x plus 2?

(−6, 0)

(6, 0)

(−2, −8) (CORRECT OPTION)

(2, −4)

QUESTION 5 - Which graph represents the function of f(x) = the quantity of 9 x squared minus 36, all over 3 x plus 6?

graph of 3 x plus 6, with discontinuity at 2, 12

graph of 3 x plus 6, with discontinuity at negative 2, 0

graph of 3 x minus 6, with discontinuity at negative 2, negative 12 (CORRECT OPTION)

graph of 3 x minus 6, with discontinuity at 2, 0
