A function for which every element of the range of the function corresponds to exactly one element of the domain. ... Note: y = f(x) is a function if it passes the vertical line test. It is a 1-1 function if it passes both the vertical line test and the horizontal line test.
A one-to-one function is a function in which the answers never repeat.
Answer:
NOTES
Step-by-step explanation:
A real numbers are numbers that can be found on a number line, they include both rational and irrational numbers.
We can first solve the equation;
x² - 6x + 9 =0, using completing square method;
x²- 6x + (-3)² = -9 + (-3)²
(x-3)² = 0
x = 3
therefore, both values of x are 3, thus the expression has no real number x is negative.
If an equation is in absolute value symbols, the answer is always positive. So this equation has no real solution.
