Martin is logging the number of strikes he bowls per hour. He has determined the function to be f(x) = 2x + 5, where x represent
s hours and f(x) represents the number of strikes he has bowled. Which of the following options describes the restrictions to the domain and range correctly? Domain, nonnegative values; range, values greater than −2.5
Domain, nonnegative values; range, values greater than or equal to 5
Domain, nonnegative values; range, values less than −2.5
Domain, nonnegative values; range, values less than or equal to 5
Domain, nonnegative values; range, values greater than −2.5 --> FALSE . The minimum value of f(x) is when x = 0, which drives to f(x) = 5 => -2.5 is no in the range.
Domain, nonnegative values; range, values greater than or equal to 5 --> TRUE. f(x) is defined for zero and all positive x, hours, and the set of images is equal or greater than 5.
Explanation: Think about it like your pluging in a number for x, like g(1) or g(x+1), but plug in the equation for f(x) g(f(x))= -(-8x^2 -5) -7 =8x^2 +5 -7 =8x^2 -2
