Which function represents g(x), a reflection of f(x) = 1/2(3)^x across the y-axisa. g(x) = 2(3)^xb. g(x) = -1/2(3)^xc. g(x) = 1/2(3)^-xd. g(x) = 2(3)^-x

Which one ? is the answer and how to find this answer

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
