As x approaches 3 from below and from above the value of the function f(x) approaches f(3) = 6. Thus the limit limx?3f(x) = 6. Question 2: Find limx?2f(x): f

Unit 1: Lesson 3 Transformations of Graphs Hour_____ Graph the following functions without using technology Feel free to use a graphing calculator to check your answer but you should be able to look at the function and apply what you learned in the lesson to move its parent function

Example 1 Consider random variables XY with pdf f(xy) such that f(x;y) = 8
The value of f (x) = |x - 3| is never negative,. For value of x < 3, the function f (x) = 3 - x which is positive. The range of the function is therefore the set [0, oo) .
What does f (x)==3 mean? It means that you have a function that every time you input a value of x gives you 3. If x = 45 then y = 3 ...if x = ? 1.234 then, again, y = 3 and so on!
[Solved] What is the domain of the function f (x) = 3x? What is the domain of the function f (x) = 3 x? The domain is the set of all possible value of x which have a finite value of f (x). Mistake Points The range of the given function will be from (0,?). 0, when x = -?, and ? when x = ?.
Is f (x) = 3x2 an exponential function? No, it is a quadratic function. An exponential function has the variable as the exponent. 3x would have been an example of an exponential function. In this function, the exponent is not variable, it is 2.
