The function f(x) = -0.3x2 + 2.5x + 5 can be used to approximate the distance a thrown ball is from the ground, where x is
the distance between the ball and the person throwing the ball. the mathematical domain of the function is all real
numbers.
the reasonable domain of the function is when 0

Find the domain and range of the following function f(x) = 51x - 21+ 4

Ihonestly have no clue if it's each or none.

City l has a temperature of −3 °f. city m has a temperature of −7 °f. use the number line shown to answer the questions: number line from negative 8 to positive 8 in increments of 1 is shown. part a: write an inequality to compare the temperatures of the two cities. (3 points) part b: explain what the inequality means in relation to the positions of these numbers on the number line. (4 points) part c: use the number line to explain which city is warmer. (3 points)
