week 13 math precalc 11

this week in math Precalc I learned about radicals and how to graph them

for example y=\frac{1}{2x+5}

so first you want to graph the parent function 2x+5

now you want to look for your invariant points (-1 and +1) then you want to draw two L shapes not touching the x intercept or the x=x int asymptotes making this

the red line doesn’t actually touch the x int even if it looks like it does because a radical is just flipping the numbers 2 is now 1/2.
