Answer:
The graph in the attached figure
Step-by-step explanation:
we have
Remember that the denominator cannot be equal to zero
so
The value of x cannot be equal to x=-2
<em>Simplify the numerator</em>
----> by difference of squares
substitute
simplify
The domain is all real numbers except the value of x=-2
The y-intercept is the point (0,-6) ---> value of y when the value of x is equal to zero)
The x-intercept is the point (2,0) ---> value of x when the value of y is equal to zero)
therefore
The graph in the attached figure
Answer:
length of the legs is
Step-by-step explanation:
the both sides of the length of the legs of a right triangle are equal
So it form a isosceles triangle 45- 45- 90 degree triangle
the ratio of 45-45-90 degree triangle is
xsqrt(2) is the side opposite to 90 degree
so
Divide both sides by square root (2)
multiply square root (2) at the top and bottom
length of the legs is
