The function of f(x) = (x-4)(x-2) What is the range of the function?
o all real numbers less than or equal to 3
all real numbers less than or equal to - 1
all real numbers greater than or equal to 3
all real numbers greater than or equal to - 1

D) All real numbers greater than or equal to -1

Step-by-step explanation:

The range is at least -1

All real numbers greater than or equal to -1

Step-by-step explanation:

f(x) = (x-4)(x-2) = x²-4x-2x+8

f(x) = x²-6x+8

f(x) = [(x)²-2(x)(3)+3²-3²]+8

f(x) = (x-3)²-9+8

f(x) = (x-3)²-1

The function has a least value of -1.

So, the range is also all real values greater than or equal to -1

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
