Given that (1,9) is on the graph of f(x), find the corresponding point for the function 2/3 f(x)

GrogVix [38]

Answer:

(1,6)

Step-by-step explanation:

If "(1, 9) is on the graph of f(x),"

then (1, [2/3][9]) is on the graph of the function y = (2/3)f(x). This works out to (1, 6).

G(x)=1/6(8)^x-5. x=9

Nezavi [6.7K]

Answer:

$g(9) = \frac{2048}{3}$

Step-by-step explanation:

Given

$g(x) = \frac{1}{6}(8)^{x-5}$

$x = 9$

Required

Solve

Substitute 9 for x in $g(x) = \frac{1}{6}(8)^{x-5}$

$g(9) = \frac{1}{6}(8)^{9-5}$

$g(9) = \frac{1}{6}(8)^{4}$

Remove bracket

$g(9) = \frac{1}{6}* 8^4$

$g(9) = \frac{1}{6}* 4096$

$g(9) = \frac{1* 4096}{6}$

$g(9) = \frac{4096}{6}$

Simplify fraction

$g(9) = \frac{2048}{3}$
