Question

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

Answer 1

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