Answer:
Step-by-step explanation:
with a 45-45-90 triangle the hypotenuse is equal to the length of one of the legs times the square root of 2.
if one of the legs is 1.2 than the hypotenuse of this triangle should be
1.2* sqrt(2) = about 1.7
The discontinuities are x=-4. Because it is a fraction, you cannot divide by zero so if the denominator is set to equal zero, which it will if x=-4, the function will be be undefined
