Step-by-step explanation:

(ƒ ∘ g)(x)

= ƒ(2x)

= (2x)² + 2(2x)

= 4x² + 4x.

Therefore (ƒ ∘ g)(2) = 4(2)² + 4(2) = 16 + 8 = 24.

Answer:

Step-by-step explanation:

g(2) = 2(2)= 4

f(4) = 4^2 + 2(4) = 16 + 8 = 24

Answer:

f(2) = 9

Step-by-step explanation:

It's give in the question,

Two different functions are,

f(x) = 4x + 1

g(x) = -2x

Then we have to find the output value of function 'f' for the input value x = 2.

By substituting the value of x in the function 'f',

f(2) = 4(2) + 1

= 9

f(2) = 9

Which equations correctly represent a line that has a slope of -2/3 and passes through the points (–2, 8) and (1, 6)?

OlgaM077 [116]

Answer:

2x + 3y = 20

Step-by-step explanation:

Slope of the line is -2/3 . We can use any of the given points to find the equation of the line. Lets use (1, 6)

The general point-slope form of a line is:

$y-y_{1} =m(x-x_{1} )$

Here m is the slope which is -2/3

x1 and y1 are the coordinates of the point. So x1 = 1 and y1 = 6

Using these values, we get:

$y-6=-\frac{2}{3} (x-1)\\\\ 3(y-6)=-2(x-1)\\\\ 3y-18=-2x+2\\\\ 2x+3y=20$
