A quadric function models the graph of a parabola. The quadratic functions y=x^2 + 3, are modeled in the graphs of the parabolas shown below. Determine which situation best represent the scenario down in the graph of the quadratic functions, y=x^2 and y=x^2 + 3. select all that apply. The quadratic function, y=x^2, has an x-intercept at the origin.
the quadratic function, y=x^2 + 3, has an x-intercept at the origin
from x = -2 to x = 0, the average rate of change for both functions is positive.
from x= -2 to x = 0, the average rate of change for both functions is negative.
for the quadratic function, y= x^2, the coordinate (2,3) is a solution to the equation of the function.
for the quadratic function, y= x^2 + 3, the coordinate (2,7) is a solution to the equation of the function.
