In Exercises 17–27, use the vertex and intercepts to sketchthe graph of each quadratic function. Give the equation of the parabola’s axis of symmetry. Use the graph to determine the function’s domain and range.
19. f(x)=(x-1)2 +2
21. y-1=(x-3)2
23. f(x)=2(x+2)2 -1
25. f(x)=4-(x-1)2
27. f(x)=x2 -2x-3
In Exercises 1–6, solve for x.
In Exercises 39–44, an equation of a quadratic function is given.
a. Determine, without graphing, whether the function has a
minimum value or a maximum value.
b. Find the minimum or maximum value and determine
where it occurs.
c. Identify the function's domain and its range.
39. f(x) = 3x – 12x – 1
41. f(x) = -4x² + &r – 3
43. f(x) = 5x? - 5x
40. f(x) = 2x? – &r – 3
42. f(x) = -2r² – 12x + 3
44. f(x) = 6x - 6x

- America is getting older. The graph shows the projected elderly U.S. population for ages 65–84 and for ages 85 and older.The formula E = 5.8√x + 56.4 models the projected number of elderly Americans ages 65–84, E, in millions, x years after 2020.a. Use the formula to find the projected increase in the number of Americans ages 65–84, in millions, from 2030 to 2060. Express this difference in simplified radicalform.b. Use a calculator and write your answer in part (a) to the nearest tenth. Does this rounded decimal overestimate or underestimate the difference in the projected data shown by the bar graph ?

Then simplify the model.arrow_forwardFor Exercises 49–52, rewrite the equation so that the coefficient on x is positive.arrow_forward
- The Mauna Loa Observatory in Hawaii records the carbon dioxide concentration y (in parts per million) in Earth’s atmosphere. The January readings for various years are shown in Figure . In the July 1990 issue of Scientific American, these data were used to predict the carbon dioxide level in Earth’s atmosphere in the year 2035, using the quadratic model y = 0.018t2 + 0.70t + 316.2 (Quadratic model for 1960–1990 data) where t = 0 represents 1960, as shown in Figure a. The data shown in figure b represent the years 1980 through 2014 and can be modeled by y = 0.014t2 + 0.66t + 320.3 (Quadratic model for 1980–2014) data where t = 0 represents 1960. What was the prediction given in the Scientific American article in 1990? Given the second model for 1980 through 2014, does this prediction for the year 2035 seem accurate?arrow_forwardYour cardiac index is your heart's output, in liters of blood per minute, divided by your body's surface area, in square meters.
