Rewrite the function by using long division to perform (80x – 8000) - (x – 110).arrow_forwardIn Exercises 5–10, find an appropriate graphing software viewing window for the given function and use it to display its graph. The win-dow should give a picture of the overall behavior of the function. There is more than one choice, but incorrect choices can miss impor-tant aspects of the function. 5. ƒ(x) = x4 - 4x3 + 15 6. ƒ(x) = x5 - 5x4 + 10 7. ƒ(x) = x sqrt(9 - x2) 8. ƒ(x) = x3 /3 - x2/ 2 - 2x + 1 9. ƒ(x) = 4x3 - x4 10. ƒ(x) = x2(6 - x3)arrow_forward
- For each of the equations in Exercises 59–62, y is defined as an implicit function of x. Solve for y, and use what you find to sketch a graph of the equation. 59. x² + y = 9 60. (x– 1)2 + (y + 2)² = 4 61. x? – 3y? = 16 62. 4y? — х? + 25 3 0arrow_forward2 Show that the line y = mx+4 will touch or intersect the curve y = x+3x+m for all values of m.arrow_forwardIn Exercises 5–8, determine whether the graph of the function is symmetricabout the y-axis, the origin, or neither.5. y = x1/5 6. y = x2/57. y = x2 - 2x - 1 8. y = e-x2arrow_forward
