Choose the function that represents the graph of the transformation of f(x) = |x| that opens down and has a vertex of (3,2)
allsm [11]

Answer:

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

Step-by-step explanation:

f(x) = |x| is shaped like a V and the vertex is at (0, 0). f(x) = -|x| is  a reflection  in the x-axis so will be an inverted V , opening down. f(x) = - |x - 3|  will be the  -|x| moved 3 units to the right with the vertex at (3, 0). To bring the vertex  to (3, 2)   it will move upwards 2 units.

So it is f(x) = -|x - 3| + 2.

Answer:

-8

Step-by-step explanation:

In order to find the answer to this question you need to use the slope formula, substitute, subtract, and simplify if needed.

(9,5),(4,1) = (x^1,y^1), (x^2,y^2)

m = \frac{y^2-y^1}{x^2-x^1} = \frac{9-1}{4-5}

9-1=8

4-5=-1

= -8

Hope this helps.
