Answer: The value of x=-1 ,when h(x)=-3
Explanation:-
The piecewise function h(x) is shown on the graph. We can see at the left side in the third quadrant x=-1 when y=-3, Thus x=-1 when h(x)=-3 .
On the right side in the fourth quadrant we also have x=2 when y=-3 ,but that point is with open circle which means that point isn't included for the function.
Therefore the value of x=-1 when h(x)= -3.

Step-by-step explanation:
If it's a straight line the use formula
m= gradient of line
c = y-intercept
we know that y-intercept is 4 so coordinate is
(0,4)
Equation also passes (2,10)
Use both coordinate to find gradient
m= vertical distance / horizontal distance
= (10-4) / (2-0)
= 3
y = 3x + 4
