Can you pleasenexaplim how to do 1 and 2. Thank you

1. (inverse functions) Find (f-1)'(2) in cach case: i. f(I) = 61 - 4 ii. f(1) = 2 and f' (1) = 1/3 iii. f(1) = Vx/(3 - VI). Note that f (4) = 2. 2. (sensor sensitivity) A sensor converts a physical quantity, such as light intensity, to a voltage which can be measured by a computer. To calibrate a light sensor you record the voltage, v, at many known light intensity values, I, and find that 73 I = f(v) = 12 + 1 For one of your data points f(0.5) = 0.1. Show that the sensitivity of this sensor (which is du/dl ) is 25/13 at v = 0.1. Hint: this question is asking you to show that (f-')'(0.1) = 25/13. I [dB]
