Please complete the follow problems neatly. Clearly label each problem, show all work, and use
Microsoft Word’s equation editor to properly format all mathematics.
1. Identify the x- and y-intercepts of 𝑦 = |𝑥 + 1| − 3
x-intercepts
y-intercepts
Sol: Sol: To find x-intercept, put y = 0 and solving for x, To find y-intercept, put x = 0 and solving for
we get
y, we get
0 = |𝑥 + 1| − 3
𝑦 = |0 + 1| − 3
3 = |𝑥 + 1|
𝑦 = |1| − 3
𝑥 + 1 = −3 , 𝑥 + 1 = 3
𝑦 =1−3
𝑥 = −3 − 1 , 𝑥 = 3 − 1
𝑦 = −2
𝑥 = −4 , 𝑥 = 2
Hence, the y-intercept is 𝑦 = −2
Hence, the x-intercepts are 𝑥 = −4, 𝑥 = 2

2. Use algebraic tests to check 𝑦 = 3𝑥 3 for symmetry with respect to:
(a) x-axis
(b) y-axis
Sol: Sol: To check symmetry w.r.t x-axis, we replace y To check symmetry w.r.t y-axis, we replace x
with −𝑦 and if the equation remains
with −𝑥 and if the equation remains
unchanged then it is symmetric otherwise
unchanged then it is symmetric otherwise not.
not. So
So
3
−𝑦 = 3𝑥
𝑦 = 3(−𝑥)3
3
𝑦 = −3𝑥
𝑦 = −3𝑥 3
The equation is not as same as original
The equation is not as same as original
