A quadratic function whose vertex is the same as the y-intercept has the equation
y=x^2+k (where k is the y-intercept, with vertex (0,k))
Since the vertex coincides with the y-intercept, the axis of symmetry is x=0.
-2/25 is the slope
x1=4
hope this helps!
Answer: 1957
Step-by-step explanation:
26 gold metals
