Boy: x
girl: x - 53
father: 4(x - 53)
Now you simplify.
Hi I’m just testing this out, sorry
Answer:
No
Step-by-step explanation:
-8 is less than -4. Negative numbers reverse the logic of positive ones: since positive 8 is more than positive 4, negative 8 is less than negative 4.
8.
First you must find the inverse of the function since that's what the f-1 means. You do this by switching the f(x) and the x and then solve for f(x).
f(x) = 2x - switch them
x = 2f(x) - now divide the 2 away
x/2 = f(x) - now put the 16 in for x to find f-1(16)
16/2 = f(x)
8 = f(x)
