Simplify the given expression.

C.

Step-by-step explanation:

Option C is correct

Step-by-step explanation:

We need to simplify the above expression.

We can write the above expression as:

Changing division sign into multiplication and reciprocating the second term we get,

Applying the power rule: a^m/a^n = a^{m-n}

Solving:

So, Option C is correct.

u what ?

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.
