The function y = - 50x + 75 is linear. So, the correct option is (A).
<h3>Define linear function.</h3>
The formula for a linear function is f(x) = mx + b, where m and b are real values. Isn't it resembling the slope-intercept form of a line, represented by the equation y = mx + b? Yes, this is the case as the graph of a linear function is a line. Here,
The line has a slope of m and a y-intercept of b.
The independent variable is "x."
The dependent variable is "y" (also known as f(x)).
Consider the equation y = - 50x + 75
Compared to the linear function equation, we get
m = -50
b = 75
So, the function is a linear function with a constant change. The function will be linear at all points.

Answer:
The answer is yes because no value of x repeats remember a function is for every value of x is exactly one output for y so if you input the same value of x and you get two different values then it's not a function
Answer:
If it is 
then it is the solution 
because the square root of an expression multiplied by itself gives that expression.
