The function is given by the formula y = 2x + 10. Find the value of the argument at which the function evaluates to -2.

Linear function of the form y = kx + b. In order to find the answer, you need to substitute the value of the function instead of y. We get 2x + 10 = -2. To find the value of the argument, it is enough to solve this equation. We transfer the parts with x to one part of the equation, and without x to the other, and do not forget about the change of signs. 2x = -10-2. Simplifying: 2x = -12. X = -12 / 2.X = -6.
Answer: if the value of the argument is -6, the function will take on the value -2.
