this is a linear equation:
f(x) = 1.5x + 3
---
table of value:
x,y
0,3
1,4.5
2,6
---
graph by drawing a line through any two points in the table
---
this is a quadratic equation:
f(x) = -xx + 4
---
table of value:
x,y
0,4
1,3
2,0
3,-5
-1,3
-2, 0
-3,-5
---
graph by drawing a line through all the points in the table

f%28x%29=1.5x%2B3 and f%28x%29=-x%5E2+%2B4

1.
f%28x%29=1.5x%2B3
make a table:
x|f%28x%29=1.5x%2B3...since linear, we need just two points
-2|0
0|3



2.
x|f%28x%29=-x%5E2+%2B4
-2|0
-1|3
0|4
1|3
2|0
-3|-5
3|-5

plot points and draw a line through:
