Logarithmic function calculator f x intercept download#

Having defined that, the logarithmic function y = log b x is the inverse function of the exponential function y = b x.

As an exercise find the domains of the above functions and compare with the domains found graphically above.Graphs of Logarithmic Function – Explanation & Examples.

Use the graph of f to determine its domain and range.

Enter 1 / (x^2 - 1) in the editing window (which means f(x) = 1 / (x^2 - 1)).

Enter sqrt(-x + 1) in the editing window (which means f(x) = sqrt(-x + 1).

Enter -2sin(x) in the editing window (which means f(x) = -2sin(x)).

Enter sqrt(x^2-9) in the editing window (which means f(x) = sqrt(x^2 - 9), sqrt means square root).

Verify graphically that the domain of f is given by the interval.

Enter sqrt(4 - x^2) in the editing window (which means f(x) = sqrt(4 - x^2), sqrt means square root).

Use the graph of f to determine whether f is even, odd or neither? Confirm your answer using analytical testsģ - Determine Domain and Range of a Function From Graph

Enter x^3+abs(x) in the editing window (which means f(x) = x^3+abs(x)).

Use the graph of f to determine whether f is even, odd or neither? Confirm your answer using analytical tests.

Enter x^3+1/x in the editing window (which means f(x) = x^3+1/x).

Enter x^3 in the editing window (which means f(x) = x^3).

Use the graph of f to determine whether f is even, odd or neither? Confirm your answer using analytical tests for even: f(x) = f(-x) and for odd: f(x) = - f(-x).

Enter x^2 + abs(x) in the editing window (which means f(x) = x^2 + abs(x), abs means absolute value).

Enter abs(x) in the editing window (which means f(x) = abs(x), abs means absolute value).

Solve the equation x^2 - 2 x - 3 = 0 and find f(0) and compare to the x and y intercepts determined graphically.

The x intercepts are found by solving x^2 - 2 x - 3 = 0 and the y intercept is given by f(0). Determine the y intercept (this is the point of intersection of the graph with the y axis). Determine (approximately) the x intercepts of the graphs (these are the points of intersection of the graph with the x axis). Enter x^2-2 x - 3 in the editing 'f(x)' window (which means f(x) = x^2 - 2 x - 3) of the graphing calculator above.x - intercept is the solution to f(x) = 0 and the y-interecept is given by f(0). Enter function 2 x - 4 in editing 'f(x)' window (which means f(x) = 2 x - 4) of the graphing calculator above and find the x and y intercepts graphically and check the answer by calculation.Interactive Tutorial 1 - x and y intercepts of graphs
