use the graph to find the following. (a) the domain of f (b) the range of f (c) the x - intercepts (d) the y - intercept (e) intervals on which f is increasing (f) intervals on which f is decreasing (g) intervals on which f is constant (h) the number at which f has a relative minimum (i) the relative minimum of f (j) f(0) (k) the values of x for which f(x)=3 (l) is f even, odd or neither? (a) what is the domain of f? (-∞,∞) (type your answer in interval notation.) (b) what is the range of f? (type your answer in interval notation.)
Answer
Explanation:
Step1: Identify the lowest and highest y - values
Observe the graph to find the minimum and maximum y - values. The graph extends infinitely upwards and has a minimum y - value at the vertex. Let's assume the vertex of the parabola (from the graph) has a y - value of (y = - 2).
Step2: Write the range in interval notation
Since the graph extends from (y=-2) (inclusive) to (+\infty), the range is ([-2,\infty)).
Answer:
([-2,\infty))
