need help worh these asap pleaseee

Find f1(x) for f(x)=x25. (for x>0) Step 1 [ Choose ] Change from f(x) to y notation: y=x25 Solve for the new y:x+5=y2(x+5)=y Swap the x s and y s: x=y25 Step 2 Rewrite in f(x) notation again: f1(x)=(x+5) Step 3 Match the function values for the exponential function f(x)=4x f(2) f(1) f(0) f(1) f(2) Put the following steps in order to solve 4x+2=8 Step 1 [ Select ] Rewrite the bases to match, 4=2,8=23 Set the exponents equal to each other. Step 2 Solve for x Use exponent rules to simplify: multiply the ex Step 3: Step 4
