number
of strikes hour, f(x)
= 2x + 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.
x = 0, f(x) = 5
x =1, f(x) = 2 + 5 =7
x = 2, f(x) = 2(2) + 5 = 9
x = 3, f(x) = 11
