I'm pretty sure the answer is 4 because, 4*21= 84.
If n = $3 then plug it in
$10 + ($6-$3)
$6-$3 = $3
$10 + $3 = $13
Irrational numbers
hope this helped :)
Same thing as before!
First, we can get rid of d(x) simply by looking at it because we can tell it's linear (it's a straight line). If we look at the table, we can see a(x) is also linear because it has a steady rate of growth. b(x) and c(x) both represent exponential growth. The curved shape of b(x) shows us this is exponential growth, and the exponent in c(x) tells us it's also exponential.
D. Only has 3 numbers in the 5-9 range, while the histogram shows 4. Hope this helps :)
