Answer:
103.
Step-by-step explanation:
If you plug in 9 for the value of x in the equation, 103 is your answer.
Answer:
f(9) = -59
Step-by-step explanation:
to find f(9), just substitue 9 for every x value in the equation
for example:
f(x) = -x² + x + 13
substitute in 9 for the x values
f(9) = -9² + 9 + 13
solve and add like terms
f(9) = -59
