Which graph represents the piecewise function? y={x+1   if  x≤0 {3x    if  x> 0

1) the last graph , note that  the center with a white circle  does not include the number zero  for the function y = 3x and the points of intersection for y = x +1  are  (-1,1)

option C

Step-by-step explanation:

y={

      {

LEts graph each equation by creating a table

y=x+1  we plug in x values less than or equal to 0

x       y=x+1

-2       -1

-1         0

0          1

Graph ordered pairs (-2,-1) (-1,0) and (0,1)

now graph the next equation

y=3x , x values are greater than 0

x     y=3x

0       0

1         3

2         0

ordered pairs  (0,0) (1,3) (2,6)

When we graph both table then we will get the graph given in option C

option C is correct

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
