Answer:
y = -2
Step-by-step explanation:
The y-intercept is the y-coordinate of the point where the curve intersects (crosses) the y-axis, i.e. when x = 0.
Therefore, to find the y-intercept, substitute x = 0 into the function:
Therefore, the curve crosses the y-axis at (0, -2) and so the y-intercept is
y = -2.
Answer:
Step-by-step explanation:
Given expression:
Let u = (x - y):
To factor a quadratic in the form find two numbers that multiply to
and sum to
:
Therefore, the numbers are: -6 and -4.
Rewrite as the sum of these two numbers:
Factor the first two terms and the last two terms separately:
Factor out the common term (u - 2):
Substitute back in u = (x - y):
Simplify:
