5) The graph of a qudratic equation has zeros
of (3, 0) and (-4, 0). Which answer could
be the equation described?
A) y=4x² – 3
B) y= (x – 3)(x + 4)
C) y=(x + 3)(x – 4)
D) y = 3x2 - 4

B) y= (x – 3)(x + 4)

Step-by-step explanation:

The graph of a qudratic equation has zeros of (3, 0) and (-4, 0).

Thus means the x-intercepts are

By the factor theorem, the factors of the associated function are:

The factored form is:

The correct answer is B

The correct answer option is tan x and cot x.

Step-by-step explanation:

We are given the following functions and we are to determine whether which of them have a range of all real numbers:

Range is the values of y which a function can take so range of tan x and cot x are all real numbers.

Period of tan x and cot x is .
