Y = f(x) = -3^x
Find fx) when x = 0.

1

Step-by-step explanation:

substitute x with 0 in the polynomial so we get,

-3^x

= -3^0

= 1 ( because any number raised to 0 is 1)

Hope it helps:)

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
