If necessary, and if your system/teacher allows it, just keep it down to 1-3 decimals.
Hope I could help! :D
f^-1(x) = sq.rt 5(x - 10)/5, sq.rt 5(x - 10)/5 is the inverse of y = 5x^2 +10
Step-by-step explanation:
interchanging the variables
x = 5y^2 + 10
5y^2 +10 = x
5y^2 = x - 10
dividing by 5
5y^2/5 = x/5 + -10/5
y^2 = x/5 + - 10/5
y^2 = x/5 - 2
y = 5 (x-10) 0/5 (sq.rt)
g(5x^2 + 10) = 5x/5
g(5x^2 + 10) = x
f^-1(x) = sq.rt 5(x - 10)/5, sq.rt 5(x - 10)/5 is the inverse of y = 5x^2 +10
Answer:
x=√y+4 or x=−√y+4
Step-by-step explanation:
Step 1: Add 4 to both sides.
x2−4+4=y+4
x2=y+4
Step 2: Take square root.
x=√y+4 or x=−√y+4
