Marley got 18 questions right on her lastest math test. When she checked her score in Aspen she saw that was 90%. How many questions were on the test?

Marcus needs to rewrite f(x) = x2 + 6x + 4 in vertex form.

Let the closed interval [a , b] be the domain of function f. the domain of f(x - 3) is given by (a) the open interval (a , b) (b) the closed interval [a , b] (c) the closed interval [a - 3 , b - 3] (d) the closed interval [a + 3 , b + 3]

How to do this , and can some one explain
