Question

Значение функции y=3x-1,5 при x =-2

Answer 1

У = 3х - 1 
у = 3 * ( -2) - 1 = - 6 - 1 =  - 7

Answer 2

У=3х-1,5
При х=-2, у=3*(-2)-1,5=-6-1,5=-7,5

Answer 3

To find the value of the function y = 3x - 1.5 when x = -2, you simply need to substitute the value of x into the equation and calculate the result.

y = 3(-2) - 1.5 y = -6 - 1.5 y = -7.5

So, when x = -2, the value of the function is y = -7.5.
