For this case we must find an expression equivalent to:

By definition of power properties we have to:

So, rewriting the expression we have:


By definition of multiplication of powers of the same base, we put the same base and add the exponents:

Answer:
Option B
ANSWER
See attachment.
EXPLANATION
The given function is

When we compare this function to

We have a=1, b=4 and c=5
We put this inside the formula for the discriminant, which is



Since the discriminant is negative, the function has no x-intercepts.
The graph of this function is the one hanging in the air above the x-axis and opens upwards.
The third option because when you factor out the denominator, you get (x-1)(x+3), giving you zeros of 1 and -3
Square root of 139:
√139 = 11.78983
