Answer:
there is no graphso i can't solve any of the question because i need to see the graph to answer the first question and i always use the first question to answer the other questions so can you attach the graph please.
Step-by-step explanation:
The interval is the value (-∞,2)
We have given that,
f(x)=x-3
g(x)= - 0.5x
<h3 /><h3>What interval is the value of (f-g)(x) negative?</h3>
First, calculate the (f-g)(x)
Since f(x)=x-3
g(x)= - 0.5x
So, (f-g)(x) = x-3-(- 0.5x)
⇒(f-g)(x) = x-3+ 0.5x
⇒(f-g)(x)
=1.5x-3
Now we are supposed to find the interval for which (f-g)(x) is negative.
So, (f-g)(x) =1.5x-3 <0
⇒1.5x<3
Thus for (f-g)(x), negative x must be less than 2
Thus the interval is(-∞,2)
Hence option B is correct.
