The range of the function f(x)=x+5 is (7,9). What is the function's domain?

1 answer:

5 0

The function is : f ( x ) = x + 5
If the range is ( 7, 9 ) we have to find the domain.
7 = x 1 + 5
x 1 = 7 - 5 = 2
9 = x 2 + 5
x 2 = 9 - 8 = 4
Answer:
The domain is : A ) ( 2, 4 )

Answer:

n = -4

Step-by-step explanation:

$(\frac{5}{3} )^2^n^+^1 * (\frac{5}{3} )^5 = (\frac{5}{3})^n^+^2$

in multiplication if the base are same u can add there exponent.

$(\frac{5}{3})^2^n^+^1^+^5 = (\frac{5}{3})^n^+^2$

base of both sides are equal so their exponent will be equal

2n + 1 + 5 = n + 2

2n + 6 = n + 2

2n - n = 2 - 6

n = -4

Simplify each expression (2a^4)^-3, a ≠ 0

sweet-ann [11.9K]

Answer:

1/(8a^12)

Step-by-step explanation:

(2a^4)^-3

Rewriting

2^-3 * a^4^-3

We know x^y^z = x^(y*z)

2^-3 * a^(4*-3)

2^-3 * a^-12

We know x^-y = 1/a^y

1/2^3 * 1/a^12

1/8 * 1/a^12

1/(8a^12)
