Use the graph of the polynomial y fx to answer the followin

Use the graph of the polynomial y = f(x) to answer the following. (a) estimate the solutions of the equation f(x) = 0. (b) What is the domain of the function? Give in interval notation (c) What is the range of the function. Give answer in interval notation.

Solution

a) the solutions of the equation f(x)=0 are the points where f(x) intersects the x axis, that is , at x= -4.5 and x=-1.5.

b)the domain of the function is the range of values that x can take, that is, here , [-0.5,-5.5]

C) the range of the function is the range of values that f(x) can take, that is, here, [-5,6]
