Answer: 121>0   121=11^2  so Discriminant is a perfect square

=> the equation has  2 roots, which real, distint  and  rational

Step-by-step explanation:

D=b^2 -4*a*c

b=5 ( coefficient near x)

a=3 (coefficient near x^2)

c=-8 ( coef without x)

D=25+4*3*8=25+96=121

121>0   121=11^2  so Discriminant is a perfect square

=> the equation has  2 roots, which real, distint  and  rational

Find the asymptotes of the function. Select all that apply.
devlian [24]

An asymptote is a vertical horizontal or oblique line to which the graph of a function progressively approaches without ever touching it.

To answer this question we observe the graph. All the values of x and y must be identified for which the graph of the function tends to infinity.

It is observed that these values are:

x = -1

x = 3

y = 0

The first two corresponds to the equations of a vertical line. The third corresponds to horizontal line, the axis of x. It can be seen that although the graph of the function is very close to these values, it never "touches" them
