What is the inverse of f of x equals 4x plus 12?
If f(x) = 4x + 12, to find the inverse, reverse the actions of the elements of the function in "reverse" order. The last thing done is "+ 12", so reverse that first by "- 12" The previous thing done was "× 4n, so reverse that by "÷ 4", but note that the divide takes precedence over subtract, so the previous step needs to be in brackets. Thus if the inverse of f(x) is g(x), g(x) = (x - 12) ÷ 4
Basic method of graphing a linear equation?
Calculate the coordinates of three points, and plot the points on the graph. Draw a straight line through them.To calculate the coordinates, assign any value for "x", replace in the equation, and solve for "y".Note that two points are enough in theory; the third is for additional verification, in case you commit some mistake.
How do you determine if you can multiply two matrices?
Tthe matrix multiplication A*Bis defined only if the number of columns in the first matrix, A, is the same as the number of rows in the second, B. Note that the condition for the multiplication of B*A will be the reverse.
