Question

у=4х-6 при каком значении аргумента значение функции равно 3; -14 0 ;-2

Answer 1

$y = 3 \ 3 = 4x - 6 \ 4x = 9 \ x = frac{9}{4} = 2 frac{1}{4}$
$y = - 14 \ - 14 = 4x - 6 \ 4x = - 8 \ x = - 2$
$y = 0 \ 0 = 4x - 6 \ 4x = 6 \ x = frac{6}{4} = 1 frac{1}{2}$
$y = - 2 \ - 2 = 4x - 6 \ 4x = 4 \ x = 1$
