Answer :
Answer:
A
Step-by-step explanation:
If you take 7-7 you get 0. if you take -8 + 8 you get 0.
The zeros of the quadratic function f(x) = (x-7)(x+8) are 7 and -8.
What are zeros of a function?
The zero of a function is any replacement for the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x‐axis; that is, the real zero of a function is the x‐intercept(s) of the graph of the function.
f(x) = (x-7)(x+8)
To calculate zeros of f(x),
f(x) = 0
(x-7)(x+8) = 0
x = 7 and x = -8
