Suppose a triangle has sides 1, 1, and 1. which of the following must be true?
a. the triangle in question may or may not be a right triangle.
b. the triangle in question is a right triangle.
c. the triangle in question is not a right triangle.

The answer would be C. The triangle in question is NOT a right triangle.

For one thing, remember that a right triangle has a HYPOTENUSE, which is the LONGEST side. This shows that not all the sides has the same length. Also, remember the Pythagorean theorem:

c² = a² + b²

This means that they cannot all be equal.

If a triangle has 3 equal sides, then the triangle is an equilateral triangle.

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
