Answer:
b
Step-by-step explanation:
The y- intercept is the point on the y- axis where the graph crosses.
On the y- axis the x- coordinate is always zero.
From the table when x = 0 , y = 3, thus
(0, 3 ) is the y- intercept → b
Answer:
The root of x = -2 + √2
Step-by-step explanation:
<u><em> Step(i):-</em></u>
Given 
⇒ 
⇒ 
⇒ 
<u><em>Step(ii):-</em></u>
Rationalizing
Apply ( a-b ) ( a+b) = a²-b²
The root of x = -2 + √2
Mathematics and science go hand in hand. The branches of science which include: Physics, astronomy, chemistry, biology, etc. In all these fields you will find that you will have to use the mathematical principles and formulae to solve the numerical problems. So, science needs maths but maths does not need science.
