Question

2. Use the function to answer the question.

f(x) = -2|x - 5| + 3

What is the vertex of the graph of f(x)?
(Points : 4)
(-5, 3)

(-2, 3)

(5, -3)

(5, 3)

Answer 1

We can begin with a model of how an equation can be changed to modify a function.
f(x)= -a(x-b)+c
A change in the number value of (a) changes the amplitude of the function, but making (a) negative also reflects it across the x axis.
A change in (b), when positive, moves the function left (b) units. But when negative, moves the function right (b) units.
A change in (c), when positive, movies the function up (c) units. But when negative, moves the function down (c) units.

So your final answer will be option four, (5,3)
