What am I doing wrong with this problem?
f(x)=3sqrt(5-x)+3

y=3sqrt(5-x)+3

3sqrt(5-x)=y-3

(3sqrt(5-x)^3=(y-3)^3

5-x=(y-3)^3
x=-(y-3)^3-5

amistre64 · Answer

y = 3rt(5-x) + 3 ; i assume you wanna invert it

x = (5-y)^(1/3) + 3

x-3 = (5-y)^(1/3)

(x-3)^3 = 5-y

(x-3)^3 -5 = -y

-(x-3)^3 +5 = y

amistre64 · Answer

that last part there; you subtracted the 5; then for got to negate it with the /-1

amistre64 · Answer

[(x-3)^3 -5 = -y] * -1

-((x-3)^3 -5) = y
