We need to cancel out the discontinuity in x = 4
In order to do that, factorize the numerator:
5x⁴ - 20x³ = 5x³(x-4)
This way, your function will be:
f(x) = <span>5x³(x-4) / (x-4)
and the two parentheses cancel out, leaving
</span>f(x) = <span>5x³
</span>
which at x = 4 gives:
f(4) = <span>5·4³</span> = 5 · 64 = 320
Therefore K = 320.
"f(x)=(5x)/(x-x²)" is the one function among the following choices given in the question that <span>has a removable discontinuity. The correct option among all the options that are given in the question is the third option or option "C". It is the only function having a term cancelling out each other at the top and the bottom. </span>
Answer:
15 students and 10 adults
Step-by-step explanation:
x + y = 25 Total number of attendants
5x + 8y = 155 Total amount earned
5(15) + 8(10) = 155 Pick numbers to sub in for x and y until you find ones that work
15 students (x) and 10 adults (y) attended the game.
