Answer 3

From the graph f(x) we can find f(x) for a few values of x:
x f(x)
0 3
1 2
2 1
3 0
4 1

Problem 52) y = f(x - 1) + 3
Find y for a few values of x
x y
1 f(1-1) + 3 = f(0) + 3 = 3 + 3 = 6 (f(0) gotten from the previous table)
2 f(2-1) + 3 = f(1) + 3 = 2 + 3 = 5
3 f(3-1) + 3 = f(2) + 3 = 1 + 3 = 4
4 f(4-1) + 3 = f(3) + 3 = 0 + 3 = 3
5 f(5-1) + 3 = f(4) + 3 = 1 + 3 = 4

So which graph does y look like?

Answer 4

There is another way to do this problem. Find the equation of f(x) from the graph. Then see what kind of horizontal and vertical translation of f(x) will lead to y = f(x - 1) + 3 and you can figure out which graph represents y = f(x - 1) + 3.

Answer 5

I don't understand :/

Answer 6

Wait would it be g?

Answer 7

If you don't follow the previous reply see the table in the reply before that.
Which graph has the points I created in the table: (1, 6), (2, 5), (3, 4), (4, 3), (5,4)?

Answer 8

Yes! g
