The answer is x-2 plz give brainliest and good luck!
Answer:
Step-by-step explanation:
f(x)= -4x+9 solve f(c+2)
f(c+2) = - 4 (c+2)+9 = -4c -8+9
f(c+2) = - 4c +1
Answer:
1 1/2 hr
Step-by-step explanation:
The correct answer is f^-1(x)=1/2x+2.
1. Substitute y for f(x). ( y=2x+4 )
2. Interchange the variables x and y. ( x=2y-4 )
3. Swap the sides. ( 2y-4=x )
4. Move the constant to the right. ( 2y=x+4 )
5. Divide both sides by 2. ( y=1/2x+2 )
6. Use substitution to substitute f^-1(x) for y.
Thus the inverse is f^-1(x)=1/2x+2
