You have the original function as 2x-5
and you are given the value of x to be -1/2
Therefore, all you have to do is substitute the value of x in the function and calculate it as follows:
f(-1/2) = 2(-1/2) - 5 = -1 -5 = -6
The numbers or measurements Being compared or called the terms of the ratio a rate is a special ratio in which the two terms are in different units we can raise our expressed as a quantity of one such as 2 ft./s or 5 mph they are called unit rates
