What is the equation of the function shown in the graph, given the equation of the parent function is f(x)=1.5^x? a. g(x)=1.5^x^-2 b. g(x)=1.5^x −2 c. g(x)=-2(1.5)^x d. g(x)=-3(1.5)^x^+1

Really need on these. i have no idea what to do

Lines a and b are parallel. what is the value of x? -5 -10 -35 -55

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
