Answer:
<h3>
f[g(x)] = 4x²+6x-3</h3>
Step-by-step explanation:
- f[g(x)]=(2x)²+3(2x)-3...substitute the values of g(x) into the function f(x)
- f[g(x)]=4x²+6x-3...simplified
To convert a decimal into scientific notation, move the decimal point until you get to the left of the first non-zero integer. The number of places the decimal point moves is the power of the exponent, because each movement represents a "power of 10".

Answer:
Step-by-step explanation:
(9x-1)^-1/2 - (x+2)(9x-1)^-1/2
= (9x-1)^-1/2( 1 - (x + 2))
= (9x-1)^-1/2(-1 - x)
= -(x + 1)(9x-1)^-1/2
= -(x + 1) / (9x-1)^1/2
Answer:
LQ = 54
Median = 69
UQ = 94
Step-by-step explanation:
This list is already sorted for you, so you don't need to worry about that, otherwise you would need to sort the numbers in ascending order. To find the median, we do 
, where n is the amount of numbers. This gives us 4, so the median is at position 4, so the median is 69. The lower quartile is simply 
, so 2, so the lower quartile is 54. The upper quartile is 
, so 6, so the upper quartile is 94.
