Find all real zeros of the function f(x)= 12 A. 5,7 B. 12 C. 1 D. none

Step-by-step explanation:

Given the function f(x) = 12, the function is only a constant with no degree. For a function to have roots, it must have at least degree of 1. Let us write the function f(x) = 12 in terms of x

f(x) = 12x⁰

From the function above it can be seen that the introduction of x⁰ can not in any way affect the function of x because x⁰ will return 1.

From the function, it can be seen that the highest power of the variable x is zero. This means that the function has no roots.

Hence, there are no real zeros of the function.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
