Answer:
check the attached picture
Step-by-step explanation:
Given function is  .
.
Now we need to make a table of values for the function rule then graph the function. 
We are free to plug any values of x like -3,-2,-1,0,1,2,3,... etc becaues domain of polynomial function is all real numbers.
Let's plug x=1 into given function to find the y-value




Hence the first point is (1,3).
Same way we can find few more points to complete the table then graph those points and connect them to get the final graph.
x	y
-2	8
-1	5
0	4
1	5
2	8

Answer:
s=40
Step-by-step explanation:
Combine s and 1/2.
150−s/2=120+1/4s
Combine 1/4and s.
150−s/2=120+s/4
Move all terms containing s to the left side of the equation.
150−3s/4=120
Move all terms not containing s to the right side of the equation.
−3s/4=−30
Multiply both sides of the equation by −4/3.
−4/3 x (−3s/4)=−4/3 x−30 => S=40
