Can someone please explain to me how to do these questions ? The coordinates of the maximum point of the graph y = f(x) are (4,3). Give the coordinates of the maximum point of the graph with equation: a) y = f(x), b) y = f(x) - 4, c) y = f(x-2) + 1?
This is a functions transformation question. What you need to know to solve this is how the addition or subtraction of a number, either within or ou...

For what values of b is (x-b) a factor of 3x^3 +(b+3)x^2 -(4b^2 +b-7)x-4?
Let f(x) = 3x^3 + (b+3)x^2 - (4b^2+b-7)x-4 Then (x-b) is a factor of f(x) if and only if f(b)=0, because if (x-b) is a factor of f(x) then we can wr...

Write the equation of the line in the form Y=MX+C. (-2,3) and (-1,4)?
How do we solve this? We can just plug the co-ordinates into the equation: y²-y¹ = m(x²-x¹) + c So substituting gives us: (4 - 3) = m (-1 - -2) + c ...

What is the difference between a variable and a constant?
A constant is held constant (as the name suggests), where as a variable is a number that is aloud to change. For instance, if we let y=5+x, here, 5 ...

How do I found out the Highest Common Multiple (HCM) of 326 and 356?
To work this out you find all the factors of 326 and all the factors of 356. Then you simple find the biggest one that they both have 326 : 1, 2, 16...

Find the integer value of x that satisfies both inequalities x + 5 > 8 and 2x - 3?
I think you maybe missing something from your question? 2x - 3....? Since we are only looking for one integer as the answer perhaps it was 2x - 3 < ...

Can someone please explain to me how to do mathematical proof by deduction?
Proof by deduction implies proving a particular property using a well known theorem or formula. For example: to show that x^2-2*x+1 >= 0 for any rea...
