Answer:
Step-by-step explanation:
The domain is correct at negative infinity to positive infinity.
The range is the lowest value of y to the highest. Our function's lowest value of y is 3 and the highest is positive infinity. The range is [3, ∞)
The x-intercepts exist where the function goes through the x-axis. Ours doesn't go through the x-axis so there are no x-intercepts.
The y-intercept is where the function goes through the y-axis. Ours is the same as the low value of the range. The y-intercept is 3.
Locate x = -1 on the axis. Find y where x = -1. When x = -1, y = 4. Likewise for when x = 1. When x = 1, y = 4
