Answer:

0 x-intercepts

Step-by-step explanation:

In order to find the x-intercepts ,you need to solve this equation

x² + 4x + 5 = 0 for x  and see how many solutions you get:

x² + 4x + 5 = 0

∆ = 4² - 4×1×5 = 16 - 20 = -4

since ∆ < 0 Then the equation has no solution then our Function has none x-intercepts.

check the graph of the function f(x) = x² + 4x + 5 (below)
