The arctangent function is the inverse function of y = tan(x).arctan(y) = tan-1(y) = x+ kπFor everyk = {...,-2,-1,0,1,2,...}For example, If the tangent of 45° is 1:tan(45°) = 1Then the arctangent of 1 is 45°:...
So the inverse of: 2x+3 is: (y−3)/2The inverse is usually shown by putting a little "-1" after the function name, like this:f-1(y)We say "f inverse of y"So, the inverse of f(x) = 2x+3 is written:f-1(y) = (y-3)/2...
f(x)=x2−4 . Determine whether it is a function and state its domain and range. Inverse Function:The inverse of a function is not always considered a function. Sometimes the inverse of a function is not a function and this happens if the given ...
Compute the inverse of a 3-by-3 matrix. Get X = [1 0 2; -1 5 0; 0 3 -9] X = 3×3 1 0 2 -1 5 0 0 3 -9 Get Y = inv(X) Y = 3×3 0.8824 -0.1176 0.1961 0.1765 0.1765 0.0392 0.0588 0.0588 -0.0980 Check the results. Ideally, Y*X produces the identity matrix...
A few coordinate pairs from the graph of the function y=14xy=14x are (−8, −2), (0, 0), and (8, 2). If we interchange the input and output of each coordinate pair of a function, the interchanged coordinate pairs would appear on the graph of the inverse function....

Find the inverse of y = 3x − 2.Here's how the inverse-finding process works: I start with my original function: y = 3x − 2 Now I'll try to solve for "x =": y+2=3xy+23=xy+23y+2=3x=x Once I have "x=", I'll switch x and y; the new "y=" is the inverse....
