Answer:
f(x)= -2(x^2-x-6)
Step-by-step
The original formula is f(x)=a(x-h)+k
1) Plug the negative 2 in for a
2) multiply (x-3)(x+2)
3) plug your answer in for 2 in for the parentheses
A) vertical angles
B) same side interior angles
C) alternate interior angles
D) corresponding angles
Its easy try it urself or use an app called Cymath
X/6+3=-18
multiply both sides by six
x+18=108
move constant to the right
x=-108-18
calculate
solution: x=-126
We are given the range of the data that is from 2.35 grams to 4.75 grams- we can call these two the lower and upper llimits respectively. In this case, to find the first class limits, we have to divide the range into 12. The range is 2.40 grams made up of 12 parts of 0.2 grams. The first class hence limits are
lower: 2.35 g
upper: 2.35+0.2 =2.55 g
