Combine like terms. (-3^2-7y-9)-(4y^2+6y+9)
1 answer:
Answer:
Step-by-step explanation:
To combine like terms we need to remove the parenthesis
Multiply negative inside the second parenthesis
Now combine like terms
The terms that has same variable are like terms
-3y^2 and -4y^2 are like terms so its -7y^2
-7y and -6y are like terms so it becomes -13y
-9 and -9 are like terms so it becomes -18

Given:
The graph of an exponential function.
To find:
The exponential growth factor as x increases by 1 unit.
Solution:
From the given graph, it is clear that the exponential function passes through the points (1,1) and (3,9). So, the equation of the exponential must must be satisfy by these points.
The general exponential function is:
...(i)
Where, a is the initial value and b is the growth factor.
Putting in (i), we get
...(ii)
Putting in (i), we get
...(iii)
Divide (iii) by (ii).
b is the the growth factor and the value of b is 3.
Therefore, the exponential growth factor is 3 as x increases by 1 unit.
