Answer:

f(g(-2)) = -3

Step-by-step explanation:

g(-2) = -2 - 3 = -5

f(-5) = 2(-5) + 7 = -10 + 7 = -3

What transformation takes the graph of f(x)=2x+3 to the graph of g(x)=2x+4 ?
Zolol [24]

The original function f(x) = 2x+3.

And the transformed function is g(x) = 2x+4.

We can see that if we add 1 into function f(x), we get

f(x) +1 or 2x+3+1 = 2x+4.

<h2>So, 1 is being added in original function f(x)  and we get g function g(x) = 2x+4.</h2>

<em>According to rules of transformations, when we add some number k in the given function, it move k units up and if we subtract k from given function, it move k units down.</em>

<h3>Therefore, correct option is B option.</h3><h3>B. translation 1 unit up.</h3>

(5).

Reading the above article I came to acknowledge that the are women only benefited because they don't metabolizes coffee in a same way as men do. so men should take more care of their coffee consumption than women.

lifestyle choices may protect one with mild form of age related memory loss from future decline. Essentially what is healthy for body is healthy for brain.

An epidemic has hit Minecole City. Its population is declining 34% every hour. In just 3 hours, there are only 25,143 people lef
Vinvika [58]
The answer is 87,455

P(x) = P(0) * nˣ
P(x) - the final population after period x
P(0) - the initial population
n - the growth factor in decimal
x - period of time

x = 3 hours
P(3) = 25,143
P(0) = ?
n = 100- 34% = 66% = 0.66


P(x) = P(0) * nˣ
25,143 = P(0) * 0.66³
25,143 = P(0) * 0.287496
P(0) = 25,143 / 0.287496
P(0) ≈ 87,455
