Find the domain and range of the following graph in interval notation. -5 4 3 2 -1 4 Domain: Range: NOTE: If you do not see an endpoint, assume that the graph continues forever in the same direction. Entry example: [2,3) or (-00,5). Enter -oo for negative infinity and oo for infinityThe revenue, R(@), of producing and selling * Awesome Hearing Aids is modeled by the function R(xx) = - 3x2 + 112x How many hearing aids need to be produced and sold in order to maximize the revenue? (Round to the nearest whole number.) The revenue is at a maximum after hearing aids are produced and sold. What is the revenue? (Round answer to the nearest cent.) The maximum revenue is $Characteristics of Linear Functions For each equation below, identify the slope and vertical-intercept Give all numbers as integers or reduced fractions. Write your intercepts as ordered pairs. If a slope or intercept does not exist, write DNE Function Slope Vertical Intercept y = - 2 y = - 70 y = 7x + 3 0 =6 y = 2+9xConsider the function graphed at right. What are the X-intercepts of the function? 10 9 87 6 5 5 5 789 10 What are the zeros of the function
