Analyze the key features of the graph of the quadratic function f(x) = -x2 + 2x + 10. a. does the parabola open up or down?
b. is the vertex a minimum or a maximum?
c. identify the axis of symmetry, vertex and the y-intercept of the parabola.

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)
