Activity: Introduction to Desmos Go to the following: https://www.desmos.com/calculator/mxhkob5yik 1. In the first line, type the (implicit) function: x + y = 3 2. In the second line, type the (explicit) function: f(x) = - x2 + 5 3. Calculate (by hand) the intercepts for x + y = 3. The y-intercept(s) of x + y = 3 is/are: The x-intercept(s) of x + y = 3 is/are: Once you find the intercept(s) algebraically, confirm your intercepts using Desmos. 4. Calculate (by hand) the intercepts for f(x) = - x2 + 5. The y-intercept(s) of f(x) is/are: The x-intercept(s) of f(x) is/are: Once you find the intercept(s) algebraically, confirm your intercepts using Desmos. 5. Calculate (by hand) the point(s) of intersection of the two graphs. The point(s) of intersection of f(x) = - x2 + 5 and x + y = 3 is/are: Once you find the point(s) of intersection algebraically, confirm them using Desmos. 6. The function h(x) = 2x+8 describes the height of a flock of flying birds (in feet above the ground) x seconds after they take flight. Use Desmos to find the intercepts (be sure you can also do this algebraically). The intercepts are: Explain in
