1 x 19 = 19
2 x 9.5 = 19
4 x 4.75 = 19
Hey there! :D
Plug in x for 2.
4x= 4(2)
x^4= (2^4)
Evaluate.
4x= 8 2^4= 16
Now, subtract the difference.
16-8= 4
The difference is 4.
I hope this helps!

In the given graph, the two lines intersects at

And intersection point is that point , where the y values of the two graphs are equal .
That is

And at x=-2, the y values are equal. THat is

So the correct option is D.
