Explain in your own words why a polynomial can’t be a quadratic if a= 0?

If , then turns into . That term goes away because it turns into 0, and adding 0 onto anything does not change the expression.

So   turns into which is a linear equation (b is the slope, c is the y intercept). It is no longer a quadratic as quadratic equations always graph out a curved parabola.

As an example, you could graph out and note how it's the exact same as , both of which are straight lines through the two points (0,4) and (1,7).

the answer would be the last one (constat) she stays at the same rat every two mintues it goes up by 0.4
