Solving rational inequalities and use sign diagram to sketch the graph. image attached for better understanding.

x ∈ (-∞ , -1) ∪ (3, ∞)

Step-by-step explanation:

The expression is already factored. Note that for the polynomial that appears in the numerator there is 1 root:

For the polynomial that appears in the denominator there is 1 root:

Note that does not belong to the domain of f(x) because it zeroes the denominator of the function and the division between zero is not defined.

With these two roots we do the study of signs to find out when

Observe the attached image

Note that:

when

when

Finally, we have the solution:

x ∈ (-∞ , -1) ∪ (3, ∞)

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
