You have two exponential functions. one function has the formula g(x) = 3(2 x ). the other function has the formula h(x) = 2 x+1. which option below gives formula for k(x) = (g – h)(x)? k(x) = 2x k(x) = 5(2x) k(x) = 5(2x+1) k(x) = 2

⇒ 1st answer

Step-by-step explanation:

* Lets explain how to solve the problem

∵

∵

- Lets revise this rule to use it

# If

- We will use this rule in h(x)

∵

- Let a = 2 , n = x , m = 1

∴

- Now lets find k(x)

∵ k(x) = (g - h)(x)

∵

∵

∴

- We have two terms with a common factor

∵ is a common factor

∵

∵

∴

*

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
