Graph the parabola. y=x²-4x+7
Plot five points on the parabola: the vertex, two points to the left of the vertex, and two points to the right of the vertex. GIVE CORDINATES

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)
