Answer:


f(x)=2x-4 for
x < -2


f(-2)=2(-2)-4=-8

Therefore, plot an open circle at (-2, -8)

Input another value of x which is less than -2 into the function. Plot this and join to create the line. As the domain of this function is
x < -2 it only has one endpoint at (-2, -8). Therefore, add an arrow to the other end to show that it continues.


f(x)=-0.5x^2 for
x\geq -2


f(-2)=-0.5(-2)^2=-2

Therefore, plot a closed circle at (-2, -2)

Input other values of x that are greater than -2 into the function and plot to help plot the curve of the function. As the domain of this function is
x \geq -2 it only has one endpoint at (-2, -2). Therefore, add an arrow to the other end to show that it continues.
