Find the largest value of the function y = -0.6x on the segment [-5; 1].

Often when you need to find the largest and smallest values of a function. it is necessary to find the derivative, equate it to zero and compare the values of the function from the critical points and the boundaries of the interval.

In our case, the function is direct proportionality, the coefficient is negative, which means that the function decreases along the entire numerical axis, since there are no gaps.

In a decreasing function, the smallest value of the argument corresponds to the largest value of the function:

y (-5) = -0.6 * (-5) = 3.
