PLEASE HELP FAST!!

determine which two equations are the same.

A. Y= -tan(x - pi/2)
B. Y= cot (x + pi/2)
C. Y= -cot(x - pi)
D. Y= -tan(x- pi)

A. a & b
B. b & d
C. a & d
D. c & d

answer:

a and b becuase i know so i need to keep talking

right

step-by-step explanation:

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
