Graph the quadratic function f(x)=−1/2x^2+7. graph the parabola by first plotting its vertex and then plotting a second point on the parabola. graph for brainliest

See picture for graph.
 Use the same steps as the first one to solve this one

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
