Now make a table for and graph the function y = 3x - 4.
X Y
-3 -13
-2 -10
-1 -7
1 -1
2 2
3 5
Graph increasing at a constant rate from left to right
Q4
Make a table of y vs. x for y = x^2. Graph y = x^2 between x = 0 and x = 3.
X Y
0 0
1 1
2 4
3 9
Graph increasing at an increasing rate from left to right.
Q5
Make a table of y vs. x for y = x^2. Graph y = x^2 between x = -3 and x = 0.
X Y
-3 9
-2 4
-1 1
0 0
Graph decreasing at a decresing rate from left to right.
Q6
Make a table of y vs. x for y = `sqrt(x). [note: `sqrt(x) means 'the square root of x']. Graph y = `sqrt(x) between x = 0 and x = 3.
X Y
0 0
1 1
2 1.41
3 1.73
Graph increasing at a decreasing rate to the right.
Q7
Make a table of y vs. x for y = 5 * 2^(-x). Graph y = 5 * 2^(-x) between x = 0 and x = 3.
X Y
0 5
1 2.5
2 1.25
3 0.625
Graph decreasing at a decreasing rate from left to right.
