Yes, it is a right triangle.

Step-by-step explanation:

Let's use Pythagorean Therom.

a^2 + b^2 = c^2

7^2 + 24^2 = 25^2

49 + 576 = 625

49 + 576 = 625

625 = 625

They both equal which proves that it's a right triangle.

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
