If
f(x+a1) = x^2 + x + 2
then what is
f(x-a)
Please help!
f(x+a1) = x^2 + x + 2
then what is
f(x-a)

Absolute value is a mathematical concept that represents the distance of a number from zero on a number line. It is always a positive value, regardless of the sign of the number.
To solve an absolute value problem, you need to isolate the absolute value expression and then consider two cases: one where the value inside the absolute value is positive, and one where it is negative. You can then solve for both cases and get two solutions.
Absolute value is commonly used in physics and engineering to represent magnitude, distance, and error. It is also used in finance to represent profit and loss, and in computer science to represent the difference between two values.
Multiplying or dividing an absolute value by a positive number will not change its value, while multiplying or dividing by a negative number will result in the absolute value becoming negative. This is because the absolute value strips away the sign of a number.
The graph of the absolute value function is a V-shaped graph, with the vertex at the origin. It is symmetric about the y-axis and has a slope of 1 on both sides of the vertex. This slope represents the rate of change of the function at any point on the graph.
