Consider the function f(x). Select all of the following that include a horizontal compression of f(x). 2f(x) f(3x) -f(x) + 1 f(0.4x) - 1 f(6x) +9 -f(0.12x)​

How to do this , and can some one explain

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
