What is the value of f(g(3))

denpristay [2]

Answer:

A

Step-by-step explanation:

f(g(3)= f(g(x=3)) = f( $\frac{3+1}{3-1}$ ) = f(4/2) = f(2) = f(x=2) = 3*2-7 = 6-7 = -1

The number of board feet in a 16 foot long tree is approximated by the model F(d) = 0.77d^2 -- 1.32d -- 9.31 where F is the numb

Lubov Fominskaja [6]

we are given

$F(d)=0.77d^2-1.32d-9.31$

where

F is the number of board feet

d is the diameter (in inches) of the log

Since, we have to minimize F

so, firstly we will find it's derivative

$F'(d)=0.77\times 2d-1.32\times 1-0$

$F'(d)=1.54d-1.32$

now, we can set it to 0

and then we can solve for d

$F'(d)=1.54d-1.32=0$

$1.54d-1.32=0$

so, we get diameter as

$d=\frac{6}{7}inch$ ..............Answer

Given f(x) is a linear function with slope 3 and y-intercept -5, what is the equation of f(x) in standard form?

lawyer [7]

The standard form:

$Ax+By=C$

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

We have m = 3 and b = -5.

Substitute:

$y=3x-5$ subtract 3x from both sides

$-3x+y=-5$ change the signs

$3x-y=5$

Multiply 2 3/4 x 1 1/3. Write your answer in simplest form

bagirrra123 [75]

so , bro to multripy fractions , you have to convert the mixed fraction into unlike fractions . so lets get started.

2 3/4 * 1 1/3

= 12 / 4 * 4/3

now multiply normally

= 48 / 12

divide this by 4/4 to get simplest for

= 12 / 3 divided by 3/3

= 4/1

Which of the following is true for the relation f(x) = x2 + 8? Only the inverse is a function. Both the equation and its inverse

Alchen [17]

<u>ANSWER</u>

Only the equation is a function

<u>EXPLANATION</u>

$f(x)=x^2+8$ is graphed above with its inverse $f^{-1}(x)=\pm \sqrt{x-8}$ .

We perform the vertical line test for both the equation and its inverse.

The equation $f(x)=x^2+8$ passed the vertical line hence it is a function.

However, $f^{-1}(x)=\pm \sqrt{x-8}$ failed the vertical line test, hence it is not a function.
