Answer:
- g(20) > f(20)
- g(x) exceeds f(x) for any x > 4
Step-by-step explanation:
As with most graphing problems not involving straight lines, it works well to start with a table of values. Pick a few values of x and compute f(x) and g(x) for those values. Plot the points and draw a smooth curve through them.
As in the attached, your table will show that there are two points of intersection between f(x) and g(x), and that for values of x more than 4, g(x) becomes much greater very quickly. Both curves rapidly reach the top of your graph space.
To find whether f(20) or g(20) is greater, you can evaluate the functions for that value of x.
f(20) = 20² = 400
g(20) = 2²⁰ = 1,048,576
Clearly, g(20) has a greater value.
Answer:40=214
Step-by-step explanation:
<span>To write this sum as a single fraction we need to put both of them over a common denominator. Our common denominator will be the simplest thing that has both 3 and 5 as a factor, which is 15 (x-2)/3 + (x+3)/5 = 5(x-2)/15 + 3(x+3)/15 Now we can put both numerators over the same denominator to get (5(x-2) + 3(x+3))/15 Next we should multiply out and simplify the numerator (5(x-2) + 3(x+3))/15 = (5x -10 +3x +9)/15 = (8x-1)/15
hope this helps but dont know if its right</span>
