Question

function g(z)=1=10z-7z
a) is the function increase or decreasing at z=0?
b)is the function increasing or decreasing at z=2?
c)does the function ever stop changing ?if yes at what value(s) of z does the function stop changing?

Answer 1

function is\[g(z)=1+10z-7z^2\]

Answer 2

f^1 (z) > 0 -------- Function Increasing


f^1 (z) < 0 -------------- Function Decreasing
