The equation d=0.3t determines the distance ,d, in km a marathon runner is from her starting point at any time ,t, in minutes. To the nearest minute, how long in hours does it take the runner to be 37 km from her starting point?

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.

In which form is the following function written? y = - 2(x – 3)(x + 5)

Which graph represents the function g(x) = |x + 4| + 2?
