It's a quadratic with a positive x² coefficient, so a CUP, with a minimum

f(x) = 2x² -12 x + 13

= 2(x² - 6x) + 13

= 2(x - 3)² - 2(9) + 13

f(x) = 2(x - 3)² - 5

Since x-3 is always zero or positive the least value is

f(3) = -5

Answer: -5

A sells to b an item at 15% profit. B sells the same item to c at 20% profit. If c pays $1656 for it. What is the price at which

andrew11 [14]

Answer:

The price at which A bought the item is $1200.

Step-by-step explanation:

Suppose, the price at which A bought the item is $x$ dollar.

A sells the item to B at 15% profit. That means, the selling price to B $= x+(0.15*x)=1.15x$ dollar.

B sells the same item to C at 20% profit. That means, the selling price to C $= 1.15x+(1.15x*0.20)=1.38x$ dollar.

Given that, C pays $1656 for the item. So, the equation will be.......

$1.38x=1656\\ \\ x=\frac{1656}{1.38}=1200$

So, the price at which A bought the item is $1200.

Et f(x) = x2 + 6 and g(x) g(x) x+8/x . Find ( g o f)( -7)

earnstyle [38]

Answer:

Step-by-step explanation:

A function composition is where one function is substituted within another function and is written g(f(x)). Here we will substitute f(x) into g(x). For g(f(-7)), we substitute -7 for x.

$\frac{x^2+6+8}{x^2+6}$

Now substitute -7 for x.

$\frac{x^2+6+8}{x^2+6} = \frac{(-7)^2+6+8}{(-7)^2+6}=\frac{49+6+8}{49+6}=\frac{63}{55}$
