The graph represents the function f(x)=x^2+3x+2

we are given

x-intercept:

we can set f(x)=0

and then we can solve for x

y-intercept:

now, we can plug x=0

Vertex:

so, vertex is (-1.5 , -0.25)

so, we can draw graph

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
