Answer:
c) None
d) At f(x) = -3, x = 0
e) the x-intercept: (-1, 0)
Step-by-step explanation:
Given:
graph of f(x) which is a piece-wise function
To find:
c) all the values of x when f(x) = -2
d) all the values of x when f(x) = -3
e) the x-intercepts
c) to determine the x values, we will trace the for x when y = -2
There is no graph line or curve at y = -2
Hence, the x value is none
d) when y = -3, the graph is an horizontal line
at y = -3, x = 0
e) The x-intercept is the value of x when y = 0
From the graph, y = 0 on the parabola
when y = 0, x = -1
In ordered form (x, y): (-1, 0)
