The relation that is a function is{ (-1,5), (-2,6), (-3,7) }. A function will not have any repeating x-values, they all have to be different.

Answer:

Option (A)

Step-by-step explanation:

Solution of two functions represented by the graph are the common points or point of intersection of the graphs.

From the graph attached,

Parabola and ellipse are intersecting each other at four points.

Therefore, solutions of the given non linear functions will be FOUR.

Option (A) will be the correct option.

Please someone explain how to solve this piecewise function!!!! Im super confused

Xelga [282]

Answer:

From top to bottom:

$0, 1, 2, -8, -8$

Step-by-step explanation:

We are given the piecewise function:

$g(x) = \left\{ \begin{array}{ll} 0.5x+1 & \text{if } x \leq 2 \\ -8 & \text{if } x > 2 \end{array} \right.$

Row 1:

We want to find g(-2).

Since -2 is less than (or equal to) 2, we will use the first equation. Thus:

$g(-2)=0.5(-2)+1=-1+1=0$

Row 2:

Likewise, 0 is less than or equal to 2. We will continue to use the first equation:

$g(0)=0.5(0)+1=1$

Row 3:

2 is not less than 2 but it is equal to 2. So we will continue to use the first equation:

$g(2)=0.5(2)+1=1+1=2$

Row 4 and 5:

Both 4 and 6 are greater than 2. Thus, we will use the second equation. Therefore:

$g(4)=-8\text{ and } g(6)=-8$
