F(x) = 5x - 2 g(x) = 2x^2−x What is f^−1(x)?

Arlecino [84]

Answer:

Set up the composite result function.

g(f (x))

Evaluate:

g (f (x))

by substituting in the value of $f$ into $g$ .

g (5x −2) = 2 (5x −2)+

Simplify each term.

Apply the distibutive property: (A b + c) = ab + ac)

g(5x−2)= 10x−4+1

Add − 4 and 1.

so, g(5x−2)=10x −3

Is 21.8 x 10 to the power of 8 a scientific notation

Oksanka [162]

Answer:

$\large\boxed{2.128\times10^9}$

Step-by-step explanation:

The scientific notation:

$a\cdot10^k\\\\1\leq a$

We have:

$21.8\times10^8$

21.8 >10

21.8 = 2.18 × 10

Thereofre:

$21.8\times10^8=2.18\times10\times10^8$

Use

$a^n\cdot a^m=a^{n+m}$

$21.8\times10^8=2.18\times10^1\times10^8=2.18\times10^{1+8}=2.18\times10^9$
