To determine if the relation y = 4x - 1 is a function, we need to check if each input (x-value) corresponds to exactly one output (y-value).
In this case, for every x-value we plug in, we will get a unique y-value. Therefore, the relation y = 4x - 1 is indeed a function.

determine the initial value and the rate of change in the following description.
last year, Joshua's tomato plant reached a maximum height of 2 feet. he is growing another tomato plant this year, and his is tracking its growth. the plant's height today is 10 inches, and it grows 1.7 inches each day.
the initial value is b= _, and the rate of change is m=_.
last year, Joshua's tomato plant reached a maximum height of 2 feet. he is growing another tomato plant this year, and his is tracking its growth. the plant's height today is 10 inches, and it grows 1.7 inches each day.
the initial value is b= _, and the rate of change is m=_.
To determine the initial value and the rate of change, we can use the formula for a linear equation, y = mx + b, where y represents the height of the tomato plant and x represents the number of days.
We are given that the initial height of the plant is 2 feet, which is equivalent to 24 inches. This initial height corresponds to the value of b in the linear equation.
b = 24 inches
We are also given that the plant's height today is 10 inches and it grows 1.7 inches each day. The growth rate of 1.7 inches per day corresponds to the value of m in the linear equation.
m = 1.7 inches
Therefore, the initial value is b = 24 inches, and the rate of change is m = 1.7 inches.
We are given that the initial height of the plant is 2 feet, which is equivalent to 24 inches. This initial height corresponds to the value of b in the linear equation.
b = 24 inches
We are also given that the plant's height today is 10 inches and it grows 1.7 inches each day. The growth rate of 1.7 inches per day corresponds to the value of m in the linear equation.
m = 1.7 inches
Therefore, the initial value is b = 24 inches, and the rate of change is m = 1.7 inches.
