Answer:

y cannot be 3, 4, or 6

Step-by-step explanation:

If the function is to have an inverse, the y-values cannot be repeated. This means ...

y ∉ {3, 4, 6}

A bakery needs to make 7 batches of muffins before opening in 4 hours. Each batch of muffins takes 2/3 hour to bake.

Evgen [1.6K]

To find 2/3 of an hour you need to spilt the hour up so you’d say each third is 20 minutes therefore, each batch of muffins takes 40 minutes, so 40*7 you get 280 and divided by 60 it’s 4.6. I don’t know what the question is exactly asking for but they will be a little bit behind schedule with their muffins

F(x)=x-3 g(x)=-0.5x for what interval is the value of (f-g)(x) negative?

yarga [219]

Answer:

(-∞, 2)

Step-by-step explanation:

Given functions:

$\begin{cases} f(x)=x-3\\g(x)=-0.5x \end{cases}$

Function composition is an operation that takes two functions and produces a third function.

The composite function (f - g)(x) means to subtract function g(x) from function f(x):

$\begin{aligned}(f-g)(x) & = f(x)-g(x)\\& = (x-3)-(-0.5x)\\& = x-3+0.5x\\& = 1.5x-3\end{aligned}$

To find the interval for which (f - g)(x) is negative, set the new function to less than zero and solve the inequality:

$\begin{aligned}(f-g)(x) & < 0\\\implies 1.5x-3 & < 0\\1.5x & < 3\\x & < \dfrac{3}{1.5}\\x & < 2\end{aligned}$

Therefore, the interval for which (f - g)(x) is negative is (-∞, 2).
