Algebra Uncomplicated: Using a Graphing Calculator

Master graphing keys and menus on a graphing calculator, including entering y equals for multiple functions, adjusting window and zoom, tracing graphs, and using the table and stat plot features.

Learn to graph linear equations on the Ti-84 graphing calculator by entering y equals one-half x minus one and using the table to plot exact points.

This lecture demonstrates graphing function types in your graphing calculator, including linear, quadratic, higher-order, rational, exponential, and logarithmic functions, with tips on window and zoom to identify asymptotes and holes.

Explore the graphing calculator's calc menu to compute values at given x, find zeros and intercepts, locate minimums and maximums, determine intersections, and access derivative and integral tools.

Graph a system of equations on a graphing calculator by entering y1 and y2, then use the calc menu to find their intersection and the exact solution (-2, 3).

Graph a system of inequalities on a graphing calculator, shading above Y > X + 5 and below Y < -2x - 1 to reveal the solution region.

Explore function operations, composition, and inverses using a graphing calculator. Learn how to evaluate f(5), compute f+g and f×g, and graph inverses.

Learn to use the stat plot feature to visualize data and perform linear regression on a graphing calculator, including entering lists, turning diagnostics on, and interpreting r and r^2.

Enter and manipulate matrices on a graphing calculator using the matrix menu, performing determinant, transpose, and reduced row echelon form to solve a system of equations.

Switch to rectangular complex mode on the graphing calculator, enter i with the second decimal key, and use parentheses to perform subtraction, multiplication, and powers including square roots of negatives.
