Question

Determine whether the formula describes y as a function of x. Explain your reasoning. y= -3x^2-7x-6

Answer 1

Answer:

Step-by-step explanation:

This is the concept of algebra, a function is defined as a relationship whereby each input has one and only one single output.

In our expression;

y=-3x^2-7x-6

this can be written as:

f(x)=-3x^2-7x-6

such that, given x=0,1,2,....

f(0)=-6,

f(1)=-16

f(2)=-32

This implies that y is a function of x.
