IN PROBLEMS 5 AND 6, function or a relation and JUSTIFY YOUR ANSWER. State whether the graph represents a of the function. Using interval notation, state the domain and range Function or Relation? both e Sot TRG fonction unction or Relation chart Domain 0,3 Range (-a IN PROBLEMS 7-9, use the given information to find the indicated function value. Use correct function notation to write your answers. (8 points) 7. Given t(-3,4). (-1.0) (2,4).(4.30. (5.), find f (-3) and f(4) 8 Given the graph of function g, at right, find g(-5) and g (o).Explanation / Answer
5.
A. function
B. Since for each value of x, there's only one value of y, so this is a fucntion.
C. values of x
Domain = [-5, 5]
D. values of y
range = [-2, 4]
2.
A. Relation.
B.
Since for some values of x, there is more than one value of y, So this cannot be a function.
OR in another words, if a vertical line cuts the graph more than one time, that cannot be function.
like when x = 3, the vertical line there's y1 = 1 and y2 = -3
C.
Domain = [-1, 5]
D.
range = (-4, 2)
