What are fractions?
Any number of equal parts is represented by a fraction, which also represents a portion of a whole. In ordinary English, a fraction refers to the number of parts of a specific size.
We are given,
1. 
As the denominator of both fractions are same we add the numerator
We get,

2. 
As the denominator of both the fractions are same we subtract the value in the numerator we get,


3. 
We first simplify the first term of the equation,

Now as the denominator is not same we use cross multiplication to perform the operation

On further simplifying we get,

Hence the answers are
1. 1
2. 
3.

I will named this exponential function as y= - 343^x .
This function is symmetrical with function y = 343^x in relation to X axis.
In general their formula is y=a^x or in your case y= - a^x
First I'll describe y=a^x => this function has domein Dx=R ( Whole field of real number), range is in interval ( 0, +infinity), when x increases and y increases, when x decreases and y decreases. This function is always positive in whole domain and always is growing function. And X axis is its asymptote (y=0).
In your case function y= - 343^x has folowing features:
domein Dx=R
range is in interval (-infinity, 0)
when x increases => y decreases =>
example: y= -2^2=-4, y= -2^3=-8 etc....
when x decreases => y increases ->
example: y= -2^(-2)= - 1/(2^2)= - 1/4, y=-2^(-3)= - 1/(2^3)= - 1/8 etc....
this function is always negative
this function is always declining
x axis is its asymptote from the top ( y=0)
It will be 84° bcs all angles equal to 180. and if you subtract 32 and 64 from 180, you’ll get 84.
its ither a or b cant tell but im more leanyent to b SOO MY FINAL AWNSER IS B
