Given the function g(x) = 2x + 1. Find the domain using the range. R:{-3, 1} D:{ }

lorasvet [3.4K]

Answer:

D = {-2, 0}

Step-by-step explanation:

If the range is {-3, 1}, that means -3 and 1 are images of some points a, b in the domain. So, there are two points a, b in the domain such that:

g(a) = -3 and g(b) = 1

If g(a) = -3 then 2a + 1 = -3 ------>2a = -4 ------> a = -2

If g(b) = 1 then 2b + 1 = 1 ------> 2b = 0 ------> b = 0

Hence D = {-2, 0}

Simplify. n 6 · n 5 ÷ n 4 · n 3 ÷ n 2 · n

trasher [3.6K]

Answer: $n^{9}$

Step-by-step explanation:

Given expression: $n^6\cdot n^5\div n^4\cdot n^3\div n^2\cdot n$

The law of exponents are given by :_

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

Using PEDMAS, first we solve division, we get

$n^6\cdot n^{5-4}\cdot n^{3-2}\cdot n\\\\=n^6\cdot n\cdot n\cdot n$

Now, using product law of exponent we get

$n^{6+1+1+1}\\\\=n^{9}$
