If the equation and graph of {eq}f(x){/eq} are known, we can write equations of graphs that are transformations of the graph of {eq}f(x) {/eq} as follows: {eq}\begin{align} &\mathsf{\text{Shift left by a units }}&&: f(x+a) \\ &\mathsf{\text{Sh...
We will find the Linear Function whose graph has a slope of (-5/6), and passes through the point (4,-8). Please click on the image to see the graph. Step 2 In order to find the Linear Function, we will use the Slope-Intercept form, which is y=mx+b. M is the slope of the...
