Sí, 7 es un número natural
Step-by-step explanation:
The median is 4.5. the median is the number in the middle
F(X) = 2x + 1
Replace f(x) with y:
Y = 2x+ 1
Switch variables:
X = 2y + 1
Solve for Y:
Subtract 1 from both sides:
X- 1 = 2y
Divide both sides by 2:
X-1 / 2 = y
Rewrite so y is in the left side:
Y = x-1 / 2
Replace y with f^-1(x):
F^-1(x) = x-1 / 2
This can also be written as x/2 - 1/2
