y = A(Bx - C)ⁿ + D
A is a vertical stretch (or shrink if |A| < 1)
B is a vertical shrink (or stretch if |B| < 1)
C is a shift to the right (or left if C is negative) → notice that Bx - C is "-C" so to take the opposite
D is a shift up (or down if D is negative)
when C = -3, it is a shift to the left 3 units
when D = -7, it is a shift down 7 units
Answer: B
-2 + 5(3x-4) =19 the answer is x = 2.733
Answer:

Step-by-step explanation:
She would need 29.5 questions which would be 70% so 29.5-18 is your answer
Answer:
2nd option
Step-by-step explanation:
Using the power rule
(a
) = na
Given
f(x) = ![\frac{3}{2\sqrt[3]{x} }](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%5Csqrt%5B3%5D%7Bx%7D%20%7D)
= 
= 
, then
f'(x) = - 
× 
= - 
× 
= - 
= - ![\frac{1}{2\sqrt[3]{x^4} }](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%5Csqrt%5B3%5D%7Bx%5E4%7D%20%7D)
[ Note there should be a leading negative ]
