A polynomial where the ends are facing downwards is an even-degree polynomial with a negative leading coefficient.
An example for this is : f(x) = -x^2
where the degree is even (2) and the leading coefficient is negative (-1).
When graphing this function, you'll find both ends pointing downwards.
Answer:
Below.
Step-by-step explanation:
Yes - those are 2 semicircles so their combined area = πr^2
= 3^2π
= 9π.
X + 8 = -x + 7
it can be set up like this :
y = x + 8
y = -x + 7
Firs month A
Second month 3A
Third month 3*3A = A (3^2)
Fourth month A(3^3)
Fith month A (3^4)
nth month A (3 ^ (n-1) )
That is an exponential model, because the variable (time, n) is the exponent of the formula.
