F(x)= 9-x^2, x ≥ 0. f^-1(x)=??
julia-pushkina [17]
y=9-x^{2},\ x\ge0

Reverse x and y:
x=9-y^{2},\ y\ge0
Solve for y:
x=9-y^{2}
\rightarrow y^{2}=9-x
\rightarrow y=\sqrt{9-x} since y\ge0

Answer:

Step-by-step explanation:

L=k/m + 2R

L-2R=K/m

K=m(L-2R)

L=4800 , R=290 , m=5/12

K=m(L-2R)

K=5/12 ( 4800-2(290))

K=5/12 (4800-580)

K=5/12(4120)

K=5275/3=1758.3
