If you would like to know what is f(2), you can
calculate this using the following steps:<span>
f(0) = 2
f(n+1) = - 2 * f(n) + 3
f(1) = - 2 * f(0) + 3 = - 2 * 2 + 3 = - 4 + 3 =
- 1
f(2) = - 2 * f(1) + 3 = - 2 * (-1) + 3 = 2 + 3 =
5
The correct result would be f(2) = 5.</span>
Answer: (7x - 2) + (4x) + (5x - 10) = 180
Explanation: The sum of all angles in a triangle is 180º, so you need to make all the angles in the triangle equal to 180º when writing an equation.
