What is the vertex of the absolute value function defined by ƒ(x) = |x - 2| - 7?
inn [45]
<h3><u>Explanation</u></h3>
  • Modulus Function

y = a |x  - h|  + k

The structure or equation is similar to a quadratic function.

The value of a determines the slope of graph.

Tthe value of h determines the horizontal shift of graph.

The value of k determines the vertical shift of the graph.

From the given equation,

f(x) =  |x - 2|  - 7

We can say that the graph shifts to the right 2 units and shifts down 7 units. Hence the vertex would be at x = 2 and y = -7. It can be written in coordinate form as (2,-7).

<h3><u>Answer</u></h3>

<u>\large{(2,-7)}</u>

Has a slope of 2 and goes through (5,1)
Slav-nsk [51]

Answer:

y = 2x - 9

Step-by-step explanation:

y= mx + b

plug in slope

y = 2x + b

plug in points

1 = 2 (5) + b

simplify

1 = 10 + b

subtract 10 each side

-9 = b

plug in to original equation

y=2x - 9
