Answer:
hello,2 th made from the wrong place.
because She should have distributed the -2 inside the parentheses.
the process should be like this;
19-2(1-x)<13
17(1-x)<13
17-17x<13
-17x<13-17 (17 goes to the opposite side as -17)
-17x<-4 (we divide each side by 17)
x= -4/-17
I hope you understand. There are errors in the first 2 parts of the question.

Step-by-step explanation:
Answer:
y = 20 
Step-by-step explanation:
Use the points to find the values of a and b
Using (0, 20 ) , then
20 = a
[ = 1 ] , then
20 = a
y = 20
Using (3, 1280 ) , then
1280 = 20 b³ ( divide both sides by 20 )
64 = b³ ( take the cube root of both sides )
![\sqrt[3]{64}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B64%7D)
= b , that is
4 = b
Then exponential function is
y = 20.
