Step-by-step explanation:
Do you mean ^2? cause if so... B don't really need crit points to solve, the parabola has a positive slope before x =2
Answer: D: Parallel to the base
Step-by-step explanation:
1. 2x+3<-3 = x<-3
You get this by subtracting 3 from both sides, which gives you -6. Then divide 2 from both sides.
2. -3x<-6 = x>2
You divide -3 from both sides. You must switch the sign because any time you multiply or divide a negative integer from both sides of an inequality the sign is switched.
3. -5x<5 = x>1
See number 2
4. 5-2x<11 = x>-3
Subtract 5 from both sides to get -2x<6. Then, divide both sides by -2 and switch the sign.
5. x+2<5 = x<3
Subtract 2 from both sides
6. 2-3x<5 = x>-1
Subtract 2 from both sides to get -3x<3. Then, divide -3 from both sides and switch the sign.
Start at (0,84) as your y-intercept because thats what he starts with. Then make a negative slope decreasing by 2 each time the x value is increased by 1
