Input functions f and g and press on the button '(f * g)(x)'. Using the graph, what do you think is the domain of f / g? Explain analytically.Ĥ - Let f(x) = sqrt(1-x^2) and g(x) = sqrt(4-x^2). Input functions f and g and press on the button '(f / g)(x)'. Using the graph, what do you think is the domain of f - g? Explain analytically.ģ - Let f(x) = 1 and g(x) = sqrt(x).

Input functions f and g and press on the button '(f - g)(x)'. Estimate the domain of (f o g) from graph? Determine the domain analytically and compare.Ģ - Let f(x) = 1 - x and g(x) = sqrt(x). Input functions f and g and press on the button '(f o g)(x)'. Is the domain of (f o g) what is expected? Explain.ġ - Let f(x) = sqrt(1-x) and g(x) = x^2. Definition: The domain of (f o g) is the set of all values of x such that g(x) is defined and real and also f(g(x)) is defined and real.(f o g)(2) and f(g(2)) should be very close if not equal. Estimate g(2) from graph (black) and now estimate f(g(2)) from graph (blue). Estimate (f o g)(2) from the graph (red). Let f(x) = sqrt(x) and g(x) = x^2, input functions f and g and press on the button '(f o g)(x)'.Is it the intersection of the domains of f and g? Why is (f/g)(x) undefined at x = 1? What is the domain of f / g? Do the same at x = 4 and some other points. Let f(x) = sqrt(x) and g(x) = x - 1, input functions f and g and press on the button '(f / g)(x)'.Explore the graph (in red) of function f / g is it what is expected? What do you think is happening at x = 0 for the graph of f / g?

Explore the domain of f + g graphically.

Explore the graph (in red) of function (f + g)(x) take some specific values of x if necessary at x = 1 for example.

Hover the mousse cursor on the top right of the graph to have the option of downloading the graph as a png file, zooming in and out, shifting the graphs. Hover the mousse cursor over the graph to trace the coordinates. Use the small letter x for the variable in the expressions of functions f and g.

(see more details on each operation below). Five operations are supported by this calculator.

If needed, Free graph paper is available. Also the argument of a function must be writtwn between brackets. NOTE: The multiplication operator * must be used explicitly whenever there is multiplication. Here is a comprehensive list of basic functions and operators that may be used.Įxamples of formulas for functions f and g, that you may copy and paste to use as inputs, are shown below: Algebraic as well as trigonometric, inverse trigonometric, exponential, logarithmic and hyperbolic functions may be used as input function. The calculator has two inputs: one for function f and a second one for function g.
