Questions + Answers key
Take MCQ Maths Test1.
Expand the polynomial f(x)=x2-3x+2 in power of (x-2)
2.
Verify Lagrange’s Mean Value theorem for \(f(x)=\sqrt { x-2 } \) in the interva [2,6]
3.
Find the equation of the tangent to the curve y2=4x+5 and which is parallel to y=2x+7
4.
Find the point on the parabola y2=18x at which the ordinate increases at twice the rate of the abscissa.
5.
Find the intervals of increasing and decreasing function for f(x) = x3 + 2x2 - 1.
1.
(x-2)+(x-2)z
2.
c = 3
3.
2x – y + 3 = 0
4.
\(\left( \frac { 9 }{ 8 } ,\frac { 9 }{ 2 } \right) \)
5.
f(x) = x3+ 2x2-1
f'(x) = 3x2 + 4x = 0
⇒ x (3x + 4) = 0
⇒ x = 0 or \(\frac { 4 }{ 3 } \)
The possible intervals are \(\left( -\infty ,-\frac { 4 }{ 3 } \right) \left( -\frac { 4 }{ 3 } ,0 \right) \) and (0, ∞).
| Interval | \(\left( -\infty ,-\frac { 4 }{ 3 } \right) \) | \(\left( -\frac { 4 }{ 3 } ,0 \right) \) | (0, ∞) |
| Sign of f'(x) | Say x = -2 3(-2)2+4(-2) = 4 +ve |
say x = -1 3(-1)2+4(-1) = -1 -ve |
say x = 1 3(1)2+4(1) = 7 +ve |
| Monotonicity | Strictly increasing | Strictly decreasing | Strictly increasing |
