Question

Use the transformations of (x)=x^2 to graph the following functions g(x)=4(x-3)^2+3

Answer 1

If you have to graph y=(x-3)^2 using f(x)=x^2, what will you do?

Answer 2

I have no idea.... need help!!

Answer 3

Test the value of y's by substituting the value of x into the formula
For y = x^2
x | -2 | -1 | 0 | 1 | 2 |
y | 4 | 1 | 0 | 1 | 4 |

For y = (x-3)^2
x | -1 | 0 | 1 | 2 | 3 | 4 | 5 |
y | | | | | | | |

Can you fill in the row of y for the second table?

Answer 4

y|1|0|1|1|3|2|5

Answer 5

is this right......

Answer 6

No o_o!
When x=-1,
y = [(-1)-3]^2 = (-4)^2 = 16
Can you try it again?

Answer 7

never mind... to frustrated thanx!!!!

Answer 8

I just need to see how you suppose to graph the function..... someone please help!!!

Answer 9

f(x-k) => shift f(x) to the right by k units
kf(x) => magnify f(x) by k units
f(x) + k => shift f(x) upwards by k units.
These are the rules you need.

Answer 10

Okay thanx!!!
