Solution:

Let the following function:


f(x)=\text{ }(1)/(2)\textx+4

The graph of this function can be obtained by applying the respective function transformations to the absolute value function y = |x|. In this case, horizontal and vertical translations and vertical shortening were used on absolute value function y = |x|.

According to the function, the vertex can be obtained by solving the following equation:


\text=0

solving for x, we get:


x\text{ = -4}

replacing this value into the function f(x) =y, we obtain:


y\text{ = }-3

so that, the vertex of this function is on the point:


(x,y)=(-4,-3)

Now, to find the x-intercept, we set the equation of the function equal to 0 and then solve for x:


0=\text{ }(1)/(2)\text-3

solving for x, we get two solutions:


x=\text{ -10}

and


x=\text{ }2

so that, the x-intercepts are the points:


(x,y)=(-10,0)

and


(x,y)=(2,0)

On the other hand, to find the y-intercept, we can evaluate the function f(x) at x=0, and then, we can solve for y:


f(0)=\text{ }(1)/(2)\text-3=(1)/(2)\text-3\text{ = 2-3 = -1}

Then, the y-intercept is on the point:


(x,y)=(0,-1)

So that, we can conclude that the correct answer is:
