The piecewise function h(x) is shown on the graph. On a coordinate plane, a piecewise function has 2 lines. The first line has a
closed circle at (negative 3, negative 7) and goes up to an open circle at (1, 1). The second line has a closed circle at (1, negative 1) and goes down to an open circle at (2, negative 3). What is the value of x when h(x) = −3? −7 −1 0 2

Answer:
Option B.
Step-by-step explanation:
It is given that h(x) is a piecewise function and it has 2 lines.
The first line has a closed circle at (-3, -7) and goes up to an open circle at (1, 1).
The second line has a closed circle at (1,-1) and goes down to an open circle at (2,-3).
The graph of piecewise function h(x) is shown below.
Since we have an open circle at (2,-3), it means x=2 is not included in the function.
From the given graph it is clear that at x=-1 the value of function is -3.
It means h(x)=-3 at x=-1.
Therefore, the correct option is B.

Answer:
Equation of line best fits the scatter plot is y =
Step-by-step explanation:
Let the equation of line be y = mx + c
where m = slope of line and c is the intercept on y -axis
from the graph intercept on y-axis is 108
and the slope of line is given by m = where (
) and (
) is the points on line
let, points be (4,96) and (18,36)
on calculating this m = =
Therefore equation of line best fits the scatter plot is y =
