8.235 X 10 -4exponent. The exponent is negative because you moved the decimal to the right instead of left :) hope this helps!

Answer:
1.5 goes in between the 0 and the first line (meaning 1) and 0.5 goes in between the left of the zero and the line before the zero
Answer:
- f^-1(x) = ±√(16 -49x^2) . . . . -4/7 ≤ x ≤ 0
- not a function
Step-by-step explanation:
The usual method of finding the inverse of a function is to solve for y the equation ...
x = f(y)
The inverse is only defined on the range of the original function, so for ...
0 ≥ x ≥ -4/7
Here, that looks like ...
x = (-1/7)√(16 -y^2)
-7x = √(16 -y^2) . . . multiply by -7
49x^2 = 16 -y^2 . . . square both sides
y^2 + 49x^2 = 16 . . . add y^2
y^2 = 16 -49x^2 . . . . subtract 49x^2
y = ±√(16 -49x^2) . . . . take the square root
So, the inverse function is ...
f^-1(x) = ±√(16 -49x^2) . . . . . defined only for -4/7 ≤ x ≤ 0
This gives two output values for each input value, so is not a function.
_____
The original f(x) is the bottom half of an ellipse, so does not pass the horizontal line test. It cannot have an inverse function.
