Explain why the function represented by the equation y=ax2+bx+c is quadratic only when a≠0.

see below

Step-by-step explanation:

y=ax^2+bx+c

Let a=0

y=0*x^2+bx+c

y = bx+c

This is the equation of a line.  It is no longer quadratic, but linear.  a cannot equal zero

it would be 6xy and -16xy.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
