Question

g(x) = 3-sqrt(x) g^-1(x) = ?

Answer 1

solve
\[x=3-\sqrt{y}\] for \(y\)

Answer 2

1) subtract 3
2) change the sign
3) square both sides

Answer 3

thanks!

Answer 4

Answer 6

sure

Answer 7

let g(x) = ax + b..... g(x+h) -g(x) / h

Answer 8

\[g(x)=ax+b\\
g(x+h)=a(x+h)+b=ax+ah+b\\
g(x+h)-g(x)=ax+ah+b-(ax+b)=ah\]

Answer 9

divide by \(h\) and you get the slope , \(a\)

Answer 10

thank you last 1, if f(x) = x^2 -1 then f(x+h) - f(x) / 2
