When a number is written in scientific notion, how can you tell right away whether or not it is or than or equal to one?
nikklg [1K]
Well, to know right away whether or not a number is equal to 1, you need to know what 1 is in scientific notation. 1 * 10^0. Easy enough :) To know if the number is greater than one, any positive number multiplied by 10^a number higher than 0 is greater than one. As well as any number greater than one multiplied by 10^0 or a positive number. For numbers less than one, the way to know is if the number is being multiplied by 10 ^ a negative number. I hope this helps :)

Find the composite function (fog)(x) given f (x) = x - 4 and g(x) = x² +1
tigry1 [53]

x² - 3 is the composite function for f(g(x)).

   • Composite functions are functions in mathematics in which the output of one function is used as the input of other function.

   • In simpler words, a composite function is a function that is generally written inside another function.

   • The function g(x) is referred to as the inner function, whereas the function f(x) is referred to as the outer function.

We have:

F(x) = x – 4

G(x) = x^2 +1

The composite function will be:

= f(g(x))

= (x^2 + 1)-4

= x^2 + 1 – 4

= x^2 – 3

As a result, the composite function for f(g(x)) is x2-3.
