What number will the function return if the input is 12.2?
36.6
How do you get a period of 3 in a cosine function?
The argument of the cosine function must be (2pi/3)*x radians
What is the zero of the function?
A zero of a function is the value of the independent variable which makes the value of the function equal to zero. Sometimes called a root of the function, as well.Example: f(x) = x - 3. The value of x, which makes f(x) = 0 is x = 3, so the zero of the function is x=3.For f(x) = x2 - 9: The values, {x=3 and x=-3} both are zeros of this function.To make it more simple, when looking at a graph, the zero is where your function crosses or touches the x-axis. These are REAL zeros. Sometimes, however, the zero might be an imaginary number. You cannot see it on the graph. So you have to work out the problem to determine ALL POSSIBLE zeros.A zero of a function is the value of the independent variable which makes the value of the function equal to zero.

Which function has a y-value of 6 if the x -value is 3?
3
What is the rate of change for the linear function y equals 2x plus 3?
