What is the function value of f(x)=xlog(x)-3 at x=2

• -3.6138
• -0.6138
• -2.3979

• -1.6138

x^3-3x+5 has a real root between

• -3 and -2

• 0 and 1
• -1 and 0
• 2 and 3

In the Newton forward interpolation the value of r is

• (x - x0) * h
• (x - x) / h^2
• (x - x0) / h
• (x - x1) / h

When we use Newton's divided difference method?

• When the data points are equally spaced.
• When the data points are randomly selected.
• When the data points are continuous.
• When the data points are unequally spaced.

Interpolation means

• Ignoring data points completely
• Deleting existing data points
• Constructing new data points within the range of a discrete set of known data points.
• Extrapolating data points beyond the known range

Which of the following is not a Numerical integration method

• Newtons forward interpoltion

• Simpsons 3/8th rule

• Trapezoidal rule
• Simpson's rule
