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.
A) For the equation 
, the slope is 
.
Slope-intercept form is y = mx + b, where m is slope and b is the y-intercept. This means that if
, the slope is .
B) Since this equation is in the same form, you just find what m is equal to.
Since
, that's the slope.
For the solution, set equal to 
, so it would be put together like this:
![y=[tex]- \frac{1}{2}x+3=2x-4\\ -\frac{1}{2}=2x-7\\ 1\frac{1}{2}x=-7\\ x=-4.66667](https://tex.z-dn.net/?f=y%3D%5Btex%5D-%20%5Cfrac%7B1%7D%7B2%7Dx%2B3%3D2x-4%5C%5C%20-%5Cfrac%7B1%7D%7B2%7D%3D2x-7%5C%5C%201%5Cfrac%7B1%7D%7B2%7Dx%3D-7%5C%5C%20x%3D-4.66667)
So your answer is -4.667.
Slope-intercept form is y = mx + b, where m is slope and b is the y-intercept. This means that if
B) Since this equation is in the same form, you just find what m is equal to.
Since
For the solution, set
So your answer is -4.667.
Bear in mind the Unit Circle is called so, because its radius is exactly 1, thus just 1 unit, the Unit Circle
