T Lesson_3_Solve_for_y_Practice.pd 100 15 12. Use the graph to the right to evaluate the following: b. f(2)= 10 c. f) = - d. Find z if f(x) = 2. e. Find x if f(x) = 8 13. Given the mapping diagram, identify the ordered pairs, complete the table and graph, then state the domain & range and determine if the relation is a function and EXPLAIN.

Answer 1

f(4) is nothing but the value of function or value of the y coordinate when x = 4

so from graph

the value of y at x= 4 is 1

so f(4) = 1

also f(2)= 0

and f(0) = 0
