Graph the equation y = –22 + 10x – 21 on the accompanying set of axes. You
must plot 5 points including the roots and the vertex. Using the graph, determine the
vertex of the parabola.

thank you for staying home

Step-by-step explanation:

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse
