Is y=x^2+8x linear, quadratic, or exponential functions?

Notice that y = x² + 8x can be written as y = x² + 8x + 0 which is in the

form y = ax² + bx + c and when a function is written in this form,

we know that it's a quadratic function.

Another way to tell that it's a quadratic function

is that the x is raised to the second power.

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
