F(x) = | 3x+1 | find the vertex of value function
PilotLPTM [1.2K]

Answer:

The vertex is the point (-\frac{1}{3},0)

Step-by-step explanation:

we know that

The general form of an absolute value equation is

y=a\left|x-h\right|+k

The variable a tells us how far the graph stretches vertically, and whether the graph opens up or down. The variables  h, and k, tell us how far the graph shifts horizontally and vertically

The vertex is the point (h,k)

we have

f(x)=\left|3x+1\right|

Rewrite the expression (3x+1)

(3x+1)=\frac{3}{3} (3x+1)=3(x+\frac{1}{3})

substitute

f(x)=\left|3(x+\frac{1}{3})\right|

f(x)=3\left|(x+\frac{1}{3})\right|

a=3\\h=-\frac{1}{3}\\k=0

therefore

The vertex is the point (-\frac{1}{3},0)

see the attached figure to better understand the problem

Really need help on these. I have no idea what to do
kirill [66]

Answer:

A

120

Step-by-step explanation:

With all the parallel lines involved, the central figure is a parallelogram.  These 4 sided figures have the odd property of having their opposite angles equal.

What that means, in plain English is that <NRL = <NML

Both of these angles = 120

Here's the cruncher. <NRL and <PRK are vertically opposite. They are therefore equal.

The answer to your question is 120 which is A
