f(x+1) = 16(x+1)² - (x+1) = 16(x²+2x+1) - x - 1
= 16x² + 32x + 16 - x - 1 = 16x²+31x+15
so
f(x+1)-f(x) = 16x²+31x+15 - (16x² - x)
= 16x²+31x+15 - 16x² + x
= 32x + 15
2.) No correlation
3.) Negative correlation
Step-by-step explanation:
Answer:
Step-by-step explanation:
$15 x 12Mths = $180
2 x 20 = $40 carlo gets back
$300 + $180 = $480
$480 - 40 = $440 is what carlo will spend in one year
Saves $40 from getting $2 back every time he works out
d i believe so it might be d if not i’m sorry
X= - 1/5
Y=5x+1
0=5x+1
-5x=1
-1/5
