Answer:
h(x) = x/2 - 1/2
Step-by-step explanation:
Here's the procedure for finding the inverse function algebraically:
1. Replace the label 'f(x)' with the label 'y:' y = 2x + 1
2. Interchange x and y: x = 2y + 1
3. Solve the resulting equation for y: 2y = x - 1, or y = (1/2)(x - 1) or y = x/2 - 1/2
This result corresponds to the 1st given possible answer choice.
The desired inverse function is h(x) = x/2 - 1/2
The original polynomial is
y =8x⁴ - 2x³ + 5
The modified polynomial, after adding 2x⁵, is
y = 2x⁵ + 8x⁴ - 2x³ + 5
Because the leading exponent is odd, therefore:
As x → -∞, y → -∞.
As x → +∞, y → +∞.
The graph confirms the conclusions.
Answer: b. The eds of the graph will extend in opposite directions.
