Question

Does this equation describe a linear function?
y=(x-11)(x-7)

Answer 1

no

Answer 2

What degree is a linear function? That is, what is the highest power of x for a linear function?

Answer 3

when we expand it out; we get an x^2 ... which makes it quadratic

Answer 4

y =ax^2 +bx+c which is a quadratic

Answer 5

To be a linear function any variables like x or y need to have only powers of 1, and no others. So if \[x^2, y^3, xy\] are in the function then it is not linear

Answer 6

as a general rule of thumb, that is correct

Answer 7

(n^2)x + n^3 is considered to be linear

Answer 8

That is because n^2 is a number as is n^3, so you have a number of x's + another number.
