Question

can you solvea. the domainb. the rangec. f(-3)d. the values of x for f(x) = -2e. the points where the graph of f crosses the x-axisf. the points where the graph of f crosses the y-axisg. the values of x for which f (x) < 0h. is f(-8) positive or negative?

Answer 1

a. The domain is [-5]&[-2]&[0]&[1]&[4]

b. The range is only [-2]

c. f(-3) is not defined.

d. Thee values of x for f(x) = -2 are: {-5, -2, 0, 1, 4}

e. The graph has no points were it touches the x-axis.

f. The graph touches the y-axis in x = 0.

g. The values of x for which f(x) < 0 are: {-5, -2, 0, 1, 4}

h. f(-8) is not defined.
