What is the vertex of y=3|x+1|-2

spin [16.1K]

Answer:

(-1,-2)

Step-by-step explanation:

Generally, the absolute value function can be expressed like so:

f(x) = y = a|x-h|+k, where vertex: (h,k)

Rewriting our function here ever so slightly gives us: y = 3|x-(-1)|+(-2)

So the vertex is at (-1,-2)

If f(x) - 3x? and g(x) = x+2, find (f•g)(x).

hammer [34]

Answer:

$-3x^{2} -6x$

Step-by-step explanation:

f(x)= - 3x

g(x) = x+2

(f•g)(x)

f(x) • g(x)

plug in

-3x • x+2

-3x(x+2)

distribute the -3x

$-3x^{2} -6x$

hope this helps!

Simplify this step by step<br> <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B-5jk%7D%7B35j%5E2k%5E2%7D%20" id="TexFormula1" tit

$\frac { -5jk }{ 35{ j }^{ 2 }{ k }^{ 2 } } \\ \\ =-\frac { 5 }{ 35 } \cdot \frac { j }{ { j }^{ 2 } } \cdot \frac { k }{ { k }^{ 2 } } \\ \\ =-\frac { 1 }{ 7 } \cdot \frac { 1 }{ j } \cdot \frac { 1 }{ k } \\ \\ =-\frac { 1 }{ 7jk }$

Remember that:

$\frac { j }{ { j }^{ 2 } } =\frac { 1 }{ j } \cdot \frac { j }{ j } =\frac { 1 }{ j } \cdot 1=\frac { 1 }{ j } \\ \\ \frac { k }{ { k }^{ 2 } } =\frac { 1 }{ k } \cdot \frac { k }{ k } =\frac { 1 }{ k } \cdot 1=\frac { 1 }{ k }$
