just plug in 101 for x
f(101) = 3(8(101) + 9)^(1/2)
f(101) = 3(817)^(1/2)
f(101) = 3(28.5832....)
f(101) = 85.749....
where "..." means im not writing out a bunch of decimals.

f(x) = 3 â( 8x +9 ) find f ( 101)
All you need to do is place 101 were the x is
f(101) = 3 â[ 8( 101) + 9 ] = 3â817 = 85.749

f(101) means substitute 101 for every x:
f (x) = 3 sqrt (8x+9)
f (101) = 3 sqrt (8(101) + 9)
f (101) = 3 sqrt (808 + 9)
f (101) = 3 sqrt (817)
f (101) â 3*28.58321
f (101) â 85.74964

f(x) = 3 sqrt (8x+9)
f(101) ------ This is showing the beginning part of the equation -- that x=101
so you put 101 in the equation
3 sqrt (8(101)+9) = ___
