We know the number of yards run per quarter:
Sum of yards run across quarters = (-2) + 14 + (-18) + (-6) = -12
Total number of quarters = 4
⇒
⇒ = -3
Hence, he ran -3 yards per quarter
Domain:
Range:
Explanation:
The function is
The domain of a function is the set of all input values for which the function is well defined. Generally, domain consists of all x-values of the function. Hence, the function is defined in the interval
.
The range of a function is the set of output values obtained by substituting the value of x in the function. Hence, the function is defined in the interval
.
