If 2 is added to five times a number the result is equal to 5 more than four times the number find the number

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.

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number?

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 5x^2 + 10x
