26 select the expressions that are equivalent to the expression below.

1st, 2nd, and last.

Step-by-step explanation:

For the first two common rules can be applied such as = and that

and for the last one this is just simplifying the radical and if you factor it you realize that, meaning that you can take the radical off of 5/8 and end up with that final answer

answer: 4

step-by-step explanation:

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
