Question

Example 1: Let f(x) = x2 +3. Evaluate f(x) at x = -1, 0, and 2. Make a table using these values.

Answer 1

the given function is:

$f(x)=x^2+3$

If x = -1, then:

$f(x)=(-1)^2+3=1+3=4$

if x = 0, then:

$f(x)=0^2+3=3$

If x = 2 then:

$f(x)=2^2+3=4+3=7$

So, a table with the values of x and f(x) is:
