Answer:

Option C, The triangle is an isosceles triangle.

Step-by-step explanation:

On a coordinate plane, triangle A B C is shown. Point A is at (negative 1, 3), point B is at (negative 5, negative 1), and point C is at (3, negative 1).

\left(-1,3\right), \left(-5,-1\right),\left(3,-1\right)

Use distance formula to find AB^2 , BC^2, CA^2\\AB^2 = (-1+5)^2+(3+1)^2 =32\\AC^2= ((-1-3)^2+(3+1)^2 = 32\\BC^2 = (-5-3)^2+(-1+1)^2 = 64

We find only two sides are equal and third side is not equal

Hence this is an isosceles triangle

Evaluate the following function over the domain {0,1,2,3}. What is the range? g (x) = -2x^{2} + 2
Alexus [3.1K]

Answer:

the range= {-16, -6, 0, 2}

Step-by-step explanation:

domain={0,1,2,3}

g(x)= -2x^{2} + 2

g(0)= -2(0)^{2} + 2 =2

g(1)= -2(1)^{2} + 2 =0

g(2)= -2(2)^{2} + 2= -6

g(3)= -2(3)^{2}+ 2= -16

the range = {-16, -6, 0, 2}
