Answer:

f(x - 4) = x^2 - 6x+ 8

Step-by-step explanation:

Given

f(x) = x^2 + 2x

Required

Find f(x - 4)

Substitute x - 4 for x

f(x - 4) = (x- 4)^2 + 2(x - 4)

Expand

f(x - 4) = x^2 - 8x + 16 + 2x - 8

Collect like terms

f(x - 4) = x^2 - 8x + 2x+ 16  - 8

f(x - 4) = x^2 - 6x+ 8

Which number had a 3 with a value that is 100 times greater than the value of the 3 in 20.342?
goblinko [34]
Here the value of 3 is =3/10
Then 100 fold of 3/10=3/10*100=30
So, the number 26538,532,97436 etc. has that property.

If f(x) = -3x + 4 and g(x) = 2, solve for the value of x for<br> which f(x) = g(x) is true.
creativ13 [48]

Answer:

the lines meet at (2/3, 2)

Step-by-step explanation:

f(x) = g(x)

plug equations for f(x) and G(x)

-3x+4 = 2

-3x = -2

x = 2/3

since both equations meet at x = 2/3, it doesn't matter which equation you plug x = 2/3 into to find the y-coordinate

for simplicity purposes since g(x) is easier to solve, I am going to plug x = 2/3 into g(x), but plugging it into f(x) will give you same answer

g(x) = 2

g(2/3) = 2

the lines meet at (2/3, 2)
