Please help Graph the following pair of quadratic functions and describe any similarities/differences observed in the graphs. a. fopens upward with a y-intercept at (2, 0); h opens downward with a y-intercept at (-2, 0)

b. fopens downward with a y-intercept at (0-2); h opens upward with a y-intercept at (0, 2)

c. fopens downward with a y-intercept at (0, 2); h opens upward with a y-intercept at (0, -2)

d. fopens upward with a y-intercept at (0, 2); h opens downward with a y-intercept at (0, -2)​
