You can clearly see that that isn't the case here: look at where gets mapped to, for instance.

PLease Explain this liNE????

#281 Re: Help Me ! » Function and limit mcq » 2017-04-05 01:37:11

Now Any one also explain about why eq of circle is not a function

#282 Re: Help Me ! » Function and limit mcq » 2017-04-05 00:51:37

Hmm, you need to find the max. and min. value of a quadratic equation. The max value of a quadratic equation is as follows:
a>0-∞
a<0--D/4a
a>1-∞
a>2-∞

What is this how you do this???

And question 1 ans is it is not a function!!!!!!

#283 Re: Help Me ! » 4 steps of approximation » 2017-04-05 00:49:29

I know this thing but see steps of approximation

#284 Re: Help Me ! » 4 steps of approximation » 2017-04-04 21:06:15

Means Dy and Dx should probably be dy and dx.

X^2+y^2=4    is function or not a function
Question 2 The function f(x)=ax^2+bx+x has Maximum value if        a>0  ,a <0, a>1,a>2
Question 3 The linear function f(x)=ax+b is identity function if a=b=0,  a=b=1, (a=1,b=0)

And I found that ln e is one in calculator but what is e^ln??? Is it possible

I think that first you should have an equation. ax+by+c is not an equation. ax+by+c = 0 is an equation. Equations have equal signs in them.


Ok it equal to zero so what we do

There is no denominator in question 1 there is x+3 remainder???

#291 Re: Help Me ! » mcq help for final exams » 2017-03-31 01:48:41

Commutative law hold In???
Inner product
Sclar product
Vector product
Cross product???????
????

#293 Re: Help Me ! » mcq help for final exams » 2017-03-31 01:46:19

No formula used there ??
How can you prove your line A line is parallel to an axis if the other axis=a constant. For e.g. y=5 will have a line parallel to the x axis.
A line is parallel if m1=m2???

How
Question 7: It depends on the function of x.
