It has e^(power).. just tried
Answer: 
Step-by-step explanation:

That is :
................. equation 1
Also

that is
................. equation 2
divide equation 2 by equation 1 , that is

x 

find the fifth root of both sides

substitute
, into equation 1 to find a , that is


multiply through by 3


To find the 11th term , the formula for the 11th term is given as :



2/3 plus 2 1/3 is 3 because 2/3+1/3=1 and 1+2=3.
Standard form
expand first then add
f(x)=3(x-7)²+5
f(x)=3(x-7)(x-7)+5
f(x)=3(x²-14x+49)+5
f(x)=3x²-42x+147+5
f(x)=3x²-42x+152
