D(7, 3), E(8, 1), and F(4, -1)
We calculate the squared distances between the points:
Since 
we have a right triangle with hypotenuse DF.
Answer:
an isosceles triangle
Step-by-step explanation:
it has two equal sides so this is isosceles triangle

Answer:
96 units^2
Step-by-step explanation:
A of parallelogram =base×height
12×8= 96 units^2
Step-by-step explanation:
f(x) = x² + 1, where x >= 0.
Let y be f(x).
=> y = x² + 1
=> x² = y - 1
=> x = √(y - 1) because x is non-negative.
Hence f^-1(x) = √(x - 1), where x >= 1.
