Find the exact solution using common logarithms 2^5x+3= 3^2x+1

AfilCa [17]

$2^{5x + 3} = 3^{2x + 1}$
$log_{2}(2^{5x + 3}) = log_{2}(3^{2x + 1})$
$(5x + 3)log_{2}(2) = (2x + 1)log_{2}(3)$
$5x + 3 = 1.58(2x + 1)$
$5x + 3 = 3.16x + 1.58$
$1.84x + 3 = 1.58$
$1.84x = -1.42$
$x \approx -0.77$

Answer:

f(-2) = 0

f(1) = 12

f(2) = 5

Step-by-step explanation:

f(-2) will lie in the function $f(x) =x^2 - 4$

$\therefore f( - 2) = {( - 2)}^{2} - 4 = 4 - 4 = 0$

f(1) will lie in the function $f(x) =2x^2 +10$

$\therefore f(1) = 2 {(1)}^{2} + 10 = 2 + 10 = 12$

f(2) will lie in the function $f(x) =5$

$\therefore f(2) = 5$
