Answer:

${x}^{2} - x + 1$

Step-by-step explanation:

subtract the functions as follows:

s(x) - r(x) = (2x+1) - (-x2 +3x)

expand the 2nd bracket by multiplying it by the negative 1 outside

= 2x + 1 + x2 - 3x

= x2 - x + 1

Voila!

Show that the equation x^3+6x-5=0 has a solution between x=0 and x=1

Mnenie [13.5K]

Answer:

Since the value of f(0) is negative and the value of f(1) is positive, then there is at least one value of x between 0 and 1 for which f(x) =0.

Step-by-step explanation:

The equation f(x) given is:

$f(x) = x^3+6x-5$

For x = 0. the value of the expression is:

$f(0) = 0^3+0-5\\f(0) = -5$

For x = 1, the value of the expression is:

$f(1) = 1^3+6-5\\f(1)=2$

Since the value of f(0) is negative and the value of f(1) is positive, then there is at least one value of x between 0 and 1 for which f(x) =0.

In other words, there is at least one solution for the equation between x=0 and x=1.
