Card 1 of 23
If (2,5)(2,5)(2,5) lies on y=f(x)y=f(x)y=f(x), what equation does this give?
A
f(2)=5f(2)=5f(2)=5
B
(x,y)⟶(x−a,y)(x,y)\longrightarrow(x-a,y)(x,y)⟶(x−a,y)
C
A change outside f(x)f(x)f(x) acts vertically, while a change inside f(x)f(x)f(x) acts horizontally.
D
- Vertical: x=−2x=-2x=−2
- Horizontal: y=3y=3y=3
