What is the midpoint of the x-intercepts of f(x) = (x – 4)(x + 4)?

Which of the following is true for the relation f(x)=2x^2+1

Which shows the graph of the solution set of 3y – 2x > –18?

David estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x. create a question you could ask that could be answered only by graphing or using a logarithm.
