What is the y-intercept, equation of the axis of symmetry and the x-coordinate of the vertex for the two following quadratic functions. f(x)=-x^2-3x+4

f(x)=2x^2-8x+5

Then make two table of values that includes the vertex. Graph the functions.

The daily production of a company is modeled by the function p = -w^2 + 75w - 1200. the daily production, p, is dependent on the number of workers (w) present. if the break-even point is when p=0, what are the least and greatest number of workers the company must have present each day in order to break even? 50 points! will give brainliest!
