How to find the derivative of a root?<span>Use the rule to differentiate the following example, first simplifying the root and writing it as a fraction using the notation. Move 7/6 forward then decrease the power by 1. Use the definition of a derivative to differentiate f(x) = x^–1 = 1/x. First simplify the numerator then simplify and cancel as much as possible.</span>
<span>equation 1/5x-2/3 y = 30, when y = 15?
so
</span><span> 1/5x-2/3 (15) = 30
1/5x - 10 = 30
1/5x = 40
x = 40(5)
x = 200

Sorry the Q dosent show all in the image
Answer:
i think this is how you do it, sorry for the bad quality, my camra is sorta broken on my computer
Step-by-step explanation:
The graph x2 only has 1 x-intercept, because it is directly on the origin.
The graph x2+2 is the parent function shifted up by 2 units. Since the lowest point is (0,2) and the graph points up, it has no x-intercepts.
