Step-by-step explanation:
because y² + 4y + 5 = (y+2)² + 1 > 0, ∀ y ∈ R
=> y² + 4y + 5 = 0 is unreasonable
=> no solutions

Answer:
g(x) is f(x) translated downward by 7 units
Step-by-step explanation:
Adding a value to a function translates its graph upward by that value. Here, -7 is added, so the graph is translated downward by 7 units.
_____
This should be no mystery. When (x, y) is plotted on a graph, the y-coordinate specifies the vertical distance from the x-axis. Then (x, y-7) would specify a vertical distance that is 7 units less. That is, the point would be 7 units lower than the point (x, y) on the graph.
