Astudent says that there is no reason to practice drawing graphs because spreadsheets can be used to draw any images desired

It is best to practice drawing graphs because not all the time you have access to spreadsheet. And spreadsheet has limited functions only. The spreadsheet cannot graph directly if you are only given the equation of certain function. By practicing to draw graphs you can also visualize the solution of certain function given.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
