Answer:
c) -4/5
d) 4/5
Step-by-step explanation:
The given equation is 25x^2 -16 = 0
Adding 16 on both sides, we get
25x^2 = 16
Dividing both sides by 25, we get
x^2 = 16/25
Taking square root on both sides, we get
x = √(16/25)
x = ±4/5
Therefore, x = 4/5 and x = -4/5
Answers: C) and D)
Hope this will helpful to understand the concept.
Thank you.
y = -2|x +1|
→ |x + 1| = -y/2
→ x+1 = y/2
and
x + 1 = -y/2
→ x + 1 belongs to R
→ x belongs to R
Domain = R
Range = y = -2(R)
→( -∞ , 0)
