Consider the function f(x) = 9x. which statement must be true? a) f(4) f(1) = f(8) f(5) b) f(4)·f(1) = f(8)·f(5) c) f(4) − f(1) = f(8) − f(5) d) f(4) − f(1) = f(−4) − f(−1)

The correct answer is A

Step-by-step explanation:

Exponential functions grow by equal factors over equal intervals because the change in x is always the same as the exponent of the quotient of the values of y.

it happens during combustion and impacts the environment because the plants and trees take in that and it can cause them to die.

y=mx+b is the final answer!   : )
