Which equation could generate the curve in the graph below?

Step-by-step explanation:

Notice that we are looking for a quadratic function that has only one real solution for y=0, that is a unique point that touches the x-axis

We need therefore to look at the discriminant associated with all 4 equations constructed by equaling y to zero. We then try to find one that gives discriminant zero , corresponding to a unique real solution to the equation.

a)  has discriminant:

b) has discriminant:

c) has discriminant:

d) has discriminant:

Therefore, the last function is the one that can have such graph

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
