Reciprocal is the quantity obtained by dividing 1 by a given quantity other than 0. The reciprocal of f(x),, is . The graphing of the reciprocals is a hyperbola. *In order to graph the reciprocal of a function, we need to find some information: – Asymptote: the invisible line that the hyperbola slowly reaches without […]
-An absolute value function has the form of y= |f(x)| where f(x) is a function. -The x-intercept of the graph of f(x) is a critical point. The graph of y=|f(x)| changes direction at this point. -The domain of y=|f(x)| is . The range is , which means that the graph always stays in quadrant 1 […]
*When graphing an inequality, there are some new things compared to graphing an equation: Solid line: use whenever “=” is involved Broken line: use when “=” is not involved Shade the region to indicate the true values of the inequality. *The steps to graph an inequality: – Identify the line or parabola that represents the […]
A quadratic function is any function that can be written in the form , where a, p, and q and . This is called the standard form, or the vertex form of the equation of a quadratic function. This form is the combination of three transformations. * The effect of changing q in . Changing […]
**In graphing linear equation, there are some formulas: y = mx + b: slope intercept form With: x,y: variables b: y-intercept m: slope. m = *All y-intercept forms are developed from the simplest form: y = x After that, the coefficient m in front of x is added, known as the slope or stretching number.
