The value -2 is a lower bound for the zeros of the function shown below f(x)=4x^3-12x^2-x+15 true or false

We are given

The value -2 is a lower bound for the zeros of the function shown below f(x)=4x^3-12x^2-x+15

So, firstly, we will find value of f(x) at x=-2

we will plug x=-2 into f(x)

we get

we will plug x=-2

now, we can simplify it

so,

we know that any zeros always lies between positive and negative value

Here , we got f(-3)=-63 ...which is negative value

so, this is lower bound

Hence , this is TRUE

true is the correct answer

Step-by-step explanation:

a p e x : )

when studying polynomials, you often hear the terms zeros, roots, factors and x x the multiplicity of a zero is important because it tells us how the graph of the let's look at the graph of a function that has the same zeros

- 70

this is the answer for you hope it
