if f{x}= negative x square - 7x - 22, what is f{negative 5}?
a.negative 82
B.NEGATIVE 32
C. 12
D. NEGATIVE 12
Your problem:
f(x) = -x^2 - 7x - 22
To find f(-5), substitute -5 for x. Watch your signs.
I hope this helps.
To find the value of f(-5), you need to substitute -5 for x in the function f(x) = -x^2 - 7x - 22.
Substituting -5 for x, we have:
f(-5) = -(-5)^2 - 7(-5) - 22
= -(25) + 35 - 22
= -25 + 35 - 22
= 10 - 22
= -12
Therefore, the answer is D. NEGATIVE 12.
