Answer:
a. f(1) = -4
b. One value of x for which f(x) = -1 : 2 (or -2)
Step-by-step explanation:
a. To find f(1), we would have to find what the value of the function would be when x = 1. By using the given graph, we can find the f(1) by finding what the y-value is when x = 1. Looking at the graph, we can see that when x = 1, y = -4. Thus, f(1) = - 4.
b. Now we are also asked to find one value of x for which f(x) = -1. In other words, what values of x would make the value of the function equal to -1? We can find values of x for which f(x) = -1 by using the graph and seeing for which x-values would the y-value be -1. We can see that y = -1 at x = -2 and x = 2. So the values of x at which f(x) = -1 are -2 and 2. You can choose either one of these values.
I hope you find my answer and explanation to be helpful. Happy studying.
Answer:
131.2
Step-by-step explanation:
There will be 18 exterior angles, each of 360/18 = 20 deg. So each interior angle, which is supplementary to the exterior angle will be 180–20 - 160 deg. The sum of the 18 interior angles = 18*160 = 2880 deg.
