Question

3. Let g(x) be the reflection of f(x) = 3x + 2 in the x­axis. What is a function rule for g(x)? (1 point)
g(x) = 3x – 2
g(x) = –3x – 2
g(x) = 3x + 2
g(x) = –3x + 2

Answer 4

multiply the function by (-1)

Answer 5

so 3* - 1 and 2 * -1?

Answer 6

so B?

Answer 7

yeah

Answer 8

omg!! thanks soo much!!! can u help me with some more?

5. What transformations change the graph of f(x) to the graph of g(x)?
f(x) = x² ; g(x) = (x + 7)² + 9
(1 point)
The graph of g(x) is the graph of f(x) translated down 7 units and to the right 9 units.
The graph of g(x) is the graph of f(x) translated up 7 units and to the left 9 units.
The graph of g(x) is the graph of f(x) translated to the right 7 units and down 9 units.
The graph of g(x) is the graph of f(x) translated to the left 7 units and up 9 units.

Answer 10

since the + 9 is on the outisde of the parentheses, we know that g(x) is f(x) shifted up 9 units

Answer 11

now, we compare the part inside the parentheses

when we have (x+h)^2 compared to x^2, we know that (x+k)^2 is shifted to the left by k units

Answer 12

*h units

Answer 13

so its d then...
