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.

Acircle has a radius of 5/6 units and is centered at (3.6, 7.8) write the equation of this circle

The fraction of defective integrated circuits produced in a photolithography process is being studied. a random sample of 300 circuits is tested, revealing 17 defectives. (a) calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool. round the answers to 4 decimal places. less-than-or-equal-to p less-than-or-equal-to (b) calculate a 95% upper confidence bound on the fraction of defective circuits. round the answer to 4 decimal places. p less-than-or-equal-to

Prove that (x-2)is factor of p (x)=2x³-3x²-17x+30
