A. True. Plug in x = 0 and it leads to y = 1.
B. False. The function is undefined when cos(x) = 0 which is when x = n*pi/2 for any odd integer n. So x = pi/2, x = 3pi/2, x = 5pi/2, etc are not allowed as input values.
C. True. This is one of the infinitely many vertical asymptotes, which result from to the fact that x = pi/2 is not allowed in the domain.
D. False. Sine can be equal to zero. The only thing we need to make sure that is nonzero is the cosine value, since secant = 1/cosine
E. False. Choice B talks about values excluded from the domain.

<h3>In summary, the answers are Choice A and Choice C</h3>
ANSWER: ⇒ ¹/₃
Solve the equation:
6a - 4 = -2
Rearrange variables to the left side of the equation:
6a = -2 + 4
Calculate the sum or difference:
6a = 2
Divide both sides of the equation by the coefficient of variable:
a = ²/₆
Cross out the common factor:
a = ¹/₃
Y = (-2/3)x + 3 is the equation
The possible value of b is:
-ax + 12x + 32 /over/ a + x
Answer:
I'm not sure but I believe it is than 0=4/5
