x^2 + 6 = -8x
Is this linear, quadratic or exponential??

Answers

Answered by MathMate
Linear will have terms containing variables not raised to any power, as well as constant terms.
Example: 2y+4x-3=0

A quadratic expression will have terms containing the variable raised to a maximum power of 2.
Example: x²+3x-4=0

An exponential expression will have terms which raise to a power containing the variable.
Example: 4<sup>x+4 - 65536 =0

So with the X being squared it would be exponential then?
Answered by MathMate
x² 's exponent does not contain x, so it is not exponential.
It is exponential when the variable (for example, x) is found in the exponent, as in 3<sup>x</sup>+4<sup>x</sup> = 5<sup>x</sup>.
So x² is NOT exponential.

If you reread the examples, it will be much clearer.
