Answer:
Step-by-step explanation:
2a. f(-3) = (-3)^2-4(-3)+6 = 9+12+6 = 27
2b. f(-2) = 3(-2)^2-(-2)^3 -2 +1 = 3(4) - (-8) -2 +1
= 12+8-1 = 19
Answer:
25
Step-by-step explanation:
maybe
Find the slope first by doing (6+2)/(4-3)=8/1 or just 8. Next use a set of coordinates into the equation so 6=8(4)+b then solve so 6=32+b next subtract 32 from both sides which would equal -24=b. Then plug it all into the equation so y=8x-24
A.
For 12 - 1,
82 - 78 = 4 degrees per hour
For 1 - 3:15,
(88 - 82) / 2.25 = 2.67 degrees per hour
For 3:15 - 4:30,
(93 - 88) / 1.25 = 4 degrees per hour
For 4:30 to 6,
(91 - 93) / 1.5 = 1.33 degrees per hour
The time intervals 12 to 1 and 3:15 to 4 had the fastest rate of change
