Question

If f(x) = x^3 , find x= -5

Answer 1

Answer:

f(-5)=-125

Step-by-step explanation:

we have

$f(x)=x^3\\\\x=-5\\\\f(-5)=(-5)^3\\\\f(-5)=-125$

Answer 2

Answer: f(-5)=-125

Step-by-step explanation:

For this problem, we are given f(x)=x³ and x=-5. Since we are given x=-5, we plug that into f(x) and solve.

f(x)=x³            [plug in x=-5]

f(-5)=(-5)³      [exponent]

f(-5)=-125

Now, we know that f(-5)=-125.
