Show that the equation x^3+7x-4=0 has a solution between x=0 and x=1
Aleksandr [31]

Step-by-step explanation:

Using the Intermediate Value Theorem, the following is applied:

"If f(x) is a continuous on interval [a,b] and we have two points f(a) and f(b) then there must be some value c such that f(a)<f(c)<f(b).

So here there must be a c such that

f(0) < f(c) < f(1)

Note: F(c)=0, the questions that the function have a solution between 0 and 1, so that means we must have some value, c such that f(c)=0 that exists

Next, plug in the x values into the function

f(0)  =  - 4

f(1) =  {1}^{3}  + 7(1) - 4 = 4

Since cubic functions are continuous and -4<0<4, then there is a solution c that lies between f(0) and f(1)

Please help!!! I would like an explanation along with your answer. Thanks

Answer:

x = 12/13

BC = 140/13

Step-by-step explanation:

If A is the mipoint of BC, then AB is half of BC.

AB = BC / 2

8x − 2 = (3x + 8) / 2

16x − 4 = 3x + 8

13x = 12

x = 12/13

BC = 3x + 8

BC = 3 (12/13) + 8

BC = 36/13 + 104/13

BC = 140/13
