Answer:
To use the vertical line test, take a ruler or other straight edge and draw a line parallel to the y-axis for any chosen value of x. If the vertical line you drew intersects the graph more than once for any value of x then the graph is not the graph of a function.

Answer:
x= 1/4 +(-1/4) √65 or x= 1/4 + 1/4 √65
Step-by-step explanation:
x= −b±√b2−4ac
/2a
x=
−(1)±√(1)2−4(−2)(8)
/2(−2)
x=
−1±√65
/−4
x= 1/4 +(-1/4) √65 or x= 1/4 + 1/4 √65
Answer:
Let C represent the total cost of each deal
Let T be the number of trips down the water slide
C = 32 for the 1st deal since the cost is the same regardless of how much she rides
C = 18 + T for the 2nd deal
To find when the two costs are equal set them equal to each other and solve for T
32 = 18 + T
T = 14 trips
The cost must be $32 since that is the only cost possible for the 1st deal

Answer:
28: x^3+4x^2+6x+4
29: 30 (4r-d)
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
Since line CE is equal to 32 and line DB is the bisector (cut into the middle) of line CE then line CF would be half of line CE. Hence the reason that line CF is equal to 16
