[Steps Shown] Answer each one as true or false: The vertex of the parabola described by f(x) = 2(x-3)^2-1 is (3, 1). The graph of f(x) = -2(x+4)^2-8 has
Question: Answer each one as true or false:
- The vertex of the parabola described by f(x) = \[2{{(x-3)}^{2}}-1\] is (3, 1).
- The graph of f(x) = \[-2{{(x+4)}^{2}}-8\] has one y-intercept and two x-intercepts.
- If f(x) = \[-{{x}^{3}}+4x\] then the graph of f falls to the left and falls to the right.
- The maximum value of y for the quadratic function f(x) = \[-{{x}^{2}}+x+1\] is 1.
