Question

spring 4v1H PRE-CLASS ASSIGNMENT Section 2.7 Group Number t BEFORE class, and TURN IT IN as you enter class Qi: Video The graph of the function is given below. Answer the following questions: i) Write fas the set of ordered pairs. Explain why fis a function. (ii) Write the domain (the set of inputs) and the range (the set of outputs) off. (ii) What is the output when the input is-2? (iv) What is the input when the output is-3? (v) If G is a relation that pairs output with its input, write G as a set of ordered pairs. Relation G is called the inverse of f (vi) Is G a function? Justify your answer. (vil) What condition should fsatisfy, so that G was a function. Q 2. To rent a jet ski at a local beach store costs 15$ plus 5S/hr. a. If you rent a jet-ski for x hours, how much will you pay? Let Ax) be the cost of renting a jet ski for x hours. b. What is the domain of f based on the situation described?

Answer 1

It is a function because forest of i/p rightarrow set of permissible o/p. domain rightarrow set of i/p x = -3, -2, -1, 0, 2, 4, 5 Range rightarrow corresponding o/p {-3, -1, 0, 2, 4} + (-2) = -1 f(x) = -3 input is 5, & -3 g is not function for single input multiple o/p. f(5), f(-3) rightarrow should have different value f(2) f(-1) also should have different value 15 $ + 5 $/hr for x hour's f(x) = 5x + 15 where x rightarrow hours 15$ is fixed price Domain will be (-infinity, infinity) time may varie from -infinity to infinity.
