For the function h(x) = 4x  x2  1, (a) determine whether the graph opens upward or downward, (b) find the axis of symmetry, (c) find the vertex, (d) find the yintercept, and (e) graph the function.
1.(a) upward, (b) x = 2, (c) (2, 3), (d) yint = 1, (e)
2.(a) downward, (b) x = 3, (c) (3, 2), (d) yint = 1, (e)
3.(a) upward, (b) x = 3, (c) (3, 2), (d) yint = 1, (e)
4.(a) downward, (b) x = 2, (c) (2, 3), (d) yint = 1, (e)

Best ResponseYou've already chosen the best response.0write terms in standard form: ax^2 +bx +c h(x) = x^2 +4x 1 If sign of a is positive > opens up negative > opens down axis of symmetry> x = b/2a vertex > take x_value from axis of symmetry and plug it into function to get y_value of vertex to find y_intercept, plug in x=0
