The required solutions of the functions are given as follows,
1. f(−7) = 35
2. f(−1) = -1
3. f(0) = 1
What is simplification?
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
1 .
for x = -7
f(x) = x² + 2x
f(-7) = (-7)² + 2(-7) = 35
2.
for x = -1
f(x) = x² + 2x
f(−1) = (-1)² + 2(-1) = -1
3.
For x = 0
f(x) = x + 1
f(0) = 0 + 1 = 1
Thus, the required solutions are given as follows,
1. f(−7) = 35
2. f(−1) = -1
3. f(0) = 1
