Which could be the function?
f(x) = (x + 4)2
f(x) = x2 + 4
f(x) = (x - 4)2
f(x) = x2 - 4
answer
C
question
The graph of f(x) = x2 is translated to form
g(x) = (x - 2)2 - 3.
Which graph represents g(x)?
answer
A
question
What is the equation of the translated function, g(x), if
f(x) = x2?
g(x) = (x - 4)2 + 6
g(x) = (x + 6)2 - 4
g(x) = (x - 6)2 - 4
g(x) = (x + 4)2 + 6
answer
D
question
The graph of g(x) is a translation of the function f(x) = x2. The vertex of g(x) is located 5 units above and 7 units to the right of the vertex of f(x). Which equation represents g(x)?
g(x) = (x + 7)2 + 5
g(x) = (x - 7)2 + 5
g(x) = (x + 5)2 + 7
g(x) = (x - 5)2 + 7
answer
B
question
Which function could be represented by the graph on the coordinate plane?
f(x) = (x - 8)2 + 6
f(x) = (x + 8)2 + 6
f(x) = (x + 8)2 - 6
f(x) = (x - 8)2 - 6
answer
D
question
