Card 1 of 23
Which coordinate is changed by a transformation outside f(x)f(x)f(x)?
A
(0,−5)(0,-5)(0,−5)
B
(x,y)↦(xa,y)(x,y)\mapsto\left(\frac{x}{a},y\right)(x,y)↦(ax,y)
C
The graph of y=f(x+a)y=f(x+a)y=f(x+a) has translation vector (−a0)\boxed{\begin{pmatrix}-a\\0\end{pmatrix}}(−a0), so f(x+3)f(x+3)f(x+3) moves left by 3 units.
D
The yyy-coordinate.
