If x = –3 is the only x-intercept of the graph of a quadratic equation, which statement best describes the discriminant of the equation? the discriminant is negative. the discriminant is –3. the discriminant is 0. the discriminant is positive

As x= -3 is the only x-intercept of the graph of a quadratic equation.

Which means that there are equal roots of the quadratic equation.

When the roots are equal then discriminant is zero.

When the roots are not real then

When the roots are real and different (unequal) then  

As in the given question x= -3 is the only root of the quadratic equation so the discriminant is zero

i think it's b

step-by-step explanation:

because the graph is 2 above (0,0)

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
