Roots/Zeros of the Function

To find the roots or zeros of the function $f(x) = (x-7)(x-2)(x+1)^2$ , we need to set the function equal to zero and solve for $x$ . The function is already factored, so we can easily find the roots by setting each factor equal to zero.

$(x-7) = 0 \implies x = 7$
$(x-2) = 0 \implies x = 2$
$(x+1)^2 = 0 \implies x+1 = 0 \implies x = -1$

Therefore, the roots or zeros of the function are $x = 7, 2, -1$ .

Even Multiplicity of the Roots

To determine the even multiplicity of the roots, we need to examine the factors of the function. The factor $(x+1)^2$ indicates that the root $x = -1$ has an even multiplicity of 2.

Degree of the Function

The degree of a polynomial function is the highest power of the variable in the function. In this case, the function is $f(x) = (x-7)(x-2)(x+1)^2$ . The highest power of $x$ is 2, which is the power of the factor $(x+1)^2$ . Therefore, the degree of the function is 2.

Leading Coefficient (LC) of the Function

The leading coefficient of a polynomial function is the coefficient of the highest power of the variable. In this case, the function is $f(x) = (x-7)(x-2)(x+1)^2$ . The highest power of $x$ is 2, and the coefficient of this term is 1. Therefore, the leading coefficient (LC) of the function is 1.

Positive or Negative Leading Coefficient (LC)

Since the leading coefficient (LC) of the function is 1, which is a positive number, the leading coefficient (LC) is positive.

Conclusion

In conclusion, the roots or zeros of the function $f(x) = (x-7)(x-2)(x+1)^2$ are $x = 7, 2, -1$ . The root $x = -1$ has an even multiplicity of 2. The degree of the function is 2. The leading coefficient (LC) of the function is 1, which is a positive number.

Example Use Case

Suppose we want to find the value of the function at $x = 3$ . We can plug in $x = 3$ into the function and evaluate it.

$f(3) = (3-7)(3-2)(3+1)^2$ $f(3) = (-4)(1)(4)^2$ $f(3) = (-4)(1)(16)$ $f(3) = -64$

Therefore, the value of the function at $x = 3$ is $-64$ .
