Please help!! :) Thank you!
Klio2033 [76]

Let's complete the square

f(x) = x^2 + 6x + 8

y = x^2 + 6x + 8

y-8 = x^2 + 6x

y-8+9 = x^2+6x+9 .... see note below

y+1 = (x+3)^2

y = (x+3)^2-1

note: I added 9 to both sides due to taking half of the 6, and then squaring that result.

We'll restrict x such that x \ge -3 to ensure that this function is one-to-one.

Now we need to swap x and y, and solve for y to get the inverse

y = (x+3)^2 - 1

x = (y+3)^2 - 1

x+1 = (y+3)^2

(y+3)^2 = x+1

y+3 = sqrt(x+1)

y = sqrt(x+1)-3

g(x) = sqrt(x+1)-3     is the inverse

The graph is shown below. The original function is in red. The inverse is in blue. The inverse is the result of reflecting the red curve over the dashed line y = x. So this explains why x and y swap places. Consequently, the domain and range also swap as well.

For f(x) = 7x +2, Find F(x) When X=0 And When X=1. Can Someone Please Help Me!!!
Romashka [77]

Hey there!

First, we'll solve for x = 0.

The first step is to replace x with 0 anytime it appears in the equation.

f(0) = 7(0) + 2

Multiply 7 by 0 next because multiplication comes before addition in PEMDAS.

f(0) = 0 + 2

Then, add 2 to 0 since it is the last step.

f(0) = 2   The value of f(x) when x = 0 is 2.

Now we can solve for x = 1.

The first step is to replace x with 1 anytime it appears in the equation.

f(1) = 7(1) + 2

Multiply 7 by 1 next because multiplication comes before addition in PEMDAS.

f(1) = 7 + 2

Then, add 2 to 7 because it is the last step.

f(1) = 9   The value of f(x) when x = 1 is 9.

Hope this helps!

Uncle Percy and the ratiolas are donating 75% of $84 where does the $84 fit in to proportion
Allisa [31]

Answer:

The answer in the procedure

Step-by-step explanation:

Let

x-----> amount corresponding to 75%

we know that

using proportion

\frac{100}{84}\frac{\%}{\$} =\frac{75}{x} \frac{\%}{\$}\\ \\ x=84*75/100\\ \\ x=\$63

Remove the parentheses from the following expression, and combine like terms.<br> 2x(y-z) + x(y+z)
wel
2x(y-z)+x(y+z)
2xy-2xz+xy+xz
like terms.(2xy+xy=3xy)(-2xz+xz=-xz)
=3xy-xz
