Which of the following functions is graphed below?

Option C.

Step-by-step explanation:

The given graph is a complex of two function.

(1) One is a straight line representing linear function

(2) Parabola representing the quadratic function.

(1) The given line has y intercept = 6 and value of functions is reducing with the value of x

Since there is a solid dot (point) at x = 1 so there will be a notation of less the equal to

Therefore, linear function is y = x + 6 x ≤ 1

(2) Parabola starts with a hollow point at x = 1

showing a vertical shift of 3 units since starting point is hollow and the value is increasing

Therefore, value of x will be greater than one and the function will be

y = x² + 3, x > 1

Finally the function are Option C.

y = x² + 3, x > 1

     x + 6, x ≤ 1

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19
