Calculate the function values for x = 2
[tex]y=x^2+4\\\\for\ x=2\to y=2^2+4=4+4=8\to(2,\ 8)\\\\y=-x+4\\\\for\ x=2\to y=-2+4=2\to(2,\ 2)[/tex]
Look at the picture.
Answer:
[tex]C.\ \left\{\begin{array}{ccc}x^2+4&.\ x<2\\-x+4&,\ x\geq2\end{array}\right[/tex]
Answer:
Option C. is the correct option.
Step-by-step explanation:
There are two portions of the given graph. One is in the curved form and second is the straight line.
In the curved portion a Hollow point is given with x coordinate as 2 and the function value of f(2) = 8.
f(x) = [tex]x^{2}+4[/tex]
f(2) = 4+4 = 8
And hollow point represents x < 2.
Similarly in the second portion of the graph which is in the form of a straight line, starting point is in the solid form which represents x ≥ 2.
The function value at x ≥ 2 is 2.
f(x) = -x + 4
f(2) = -2 + 4 = 2
Therefore Option C. is the correct answer.
