Question

How to find value of -a

Answer 1

Given details:

A function of $x$ is defined by

$\quad f(x)=x^{2}$

To find:

The value of $f(x)$ when $x=-a$

Step-by-step explanation:

• We can find $f(x)$ for any given value of $x$ by simply substituting it.
• We must remember that, the square of any negative number or term results in a positive value or term, i.e., $(-s)^{2}=s^{2}$

When $x=-5,f(x)=(-5)^{2}=5^{2}=25$

When $x=-4,f(x)=(-4)^{2}=4^{2}=16$

When $x=-3,f(x)=(-3)^{2}=3^{2}=9$

When $x=-2,f(x)=(-2)^{2}=2^{2}=4$

When $x=-1,f(x)=(-1)^{2}=1^{2}=1$

When $x=-a,f(x)=(-a)^{2}=a^{2}$

Answer:

For $x=-a,$ the value of $f(x)$ is $a^{2}.$

Answer 2

Answer:

f
