Find the value of 2[3(x^2 – 5) + 5y] when x = 9 and y = 3.
The population of a country increased by an average of 2% per year from 2000 to 2003. If the population of this country was 2 000 000 on December 31, 2003, then the population of this country on January 1, 2000, to the nearest thousand would have been
If Logx (1 / 8) = – 3 / 2, then x is equal to
f is a quadratic function whose graph is a parabola opening upward and has a vertex on the x-axis. The graph of the new function g defined by g(x) = 2 – f(x – 5) has a range defined by the interval.
If the graph of y = f(x) is transformed into the graph of 2y – 6 = – 4 f(x – 3), point (a , b) on the graph of y = f(x) becomes point (A , B) on the graph of 2y – 6 = – 4 f(x – 3) where A and B are given by.
