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)

HELP ME PLEASEEEEE PLEAZEEEEEEE ASAP :(

Hi!
The correct answer is B, 1.997 • 10^2

This can be found by simply moving the decimal
place over x times (x represents the exponent). For example, if it were 1.12 • 10^2, you’d move your decimal place over 2 places to the right because it is positive (move left if negative).
