Question details

Pre-Cakculus, CA1.3 Page 11 Pre-calculus Introduction to Functions NomeMono Mandoa 1. Definition of Function a. With your partner(s), write down an example function: b. Class Discussian: What about your example function makes it a function? (Try describing precisely what your example function does) Based on the class discussion above, write a definition for function: A function is... 2. Numerical Representation: Consider the following table of input values and associated output values. 17 .8 Does this table represent a function? Why or why not? If not, then adjust it (as little as possible) so that it is a function, f(x). (Make any adjustments in the table above.) a. Represent your function, f(x), in at least one other form (graphical, symbolic or in words). Is it exactly the same function? b.
Pre-Calculus, CA L3 Pase12 The set of all input values for a function is called the domain of the function and the set of all associated output values is called the range of the function. c. State the domain and range of your function,) Domain: Range: d. Functional Notation: Fill in the following blanks:
Pre-Calculus, CA L3 Page la Symbolic Representation: Consider the symbolic formula below where C is chirp rate (in chirps per minute) for a particular type of cricket and T is temperature (in degrees Fahrenheit). This is only valid for positive chirp rates and for temperatures less than 136 degrees Fahrenheit, the highest temperature ever recorded at a weather station. 3. C=4T-160 Does this symbolic formula represent a function? Why or why not? If not, then adjust it (as little as possible) so that it is a function, C(T). a. Represent your function, C(CT), in at least one other form (graphical, numerical or in words) Is it exactly the same function? b. c. State the domain and range of your function, C(T) Domain: Range: what d. If you hear one of these crickets chirping at a rate of 164 chirps per minute, then would you predict the temperature to be?
Pre-Caculus, CA L Patel Find C(52) and explain the meaning of C(52) Use complete sentences in English. e. 4 Graphical Representotion: Consider the following eragh Does this graph represent a function? Why or why not? If not, then adjust it (as little as possible) so that it is a function, y =f(x). a. b. State the domain and range of your function, f(x). Domain: Range c. Find (approximately from the graph) the value of f (3) d. Find (approximately from the graph) all x for which f(x) 1: Le., solve f(x) 1 for x
