What are the domain restrictions of a + 1 / a^2-5a-36?

1 answer:

3 0

All real numbers except -4 and 9.

The domain of an expression is the range of all values for which the expression is defined. Looking at the expression, it will legal everywhere except when a^2 - 5a - 36 is equal to 0. Since that's a quadratic equation, we can use the quadratic formula to find where its value is 0, giving -4 and 9.

Therefore the domain of the expression is, All real numbers except -4 and 9.

hoa [83]

Answer:

y 》 2

y > -x + 3

Step-by-step explanation:

Equation of the bold line:

m = (-3/3) = -1

y = -x + 3

Shaded region is below y=2 (dotted)

So, it's defined by y < 2

Also, it's below the bold line

y 《 - x + 3

Everything outside these is not shaded:

y 》2

and y > -x + 3
