The graph of the function f(x)= -(x+3)(x-1) is shown below. What is true about the domain and range of the function?
1 answer:
Answer:
The domain is all real numbers, and the range is all real
numbers less than or equal to 4.
Step-by-step explanation:
The domain of a function f(x) is the set of all values for which the function is defined
We are given
f(x) is defined for all real values of x since there are no restrictions on the value of x
So,The domain of the function is all real numbers
Range of the function is the set of all values that f takes.
So, Range of given function is all real numbers less than or equal to 4.
Hence The domain is all real numbers, and the range is all real numbers less than or equal to 4.

Answer:
see below
Step-by-step explanation:
All of the given data sets have x-values that are sequential with a difference of 1. That makes it easy to determine the sort of sequence the y-values make.
<u>first choice</u>: the y-values have a common difference of -2. This will be matched by a linear model.
<u>second choice</u>: the y-values have a common difference of +2. Again, this will be matched by a linear model.
<u>third choice</u>: the y-values have a common ratio of -2. This will be matched by an exponential model.
<u>fourth choice</u>: the y-value differences are 3, 5, 7, increasing by a constant amount (2). This is characteristic of a sequence that has a quadratic model.
