Question:

The function f(x) is defined as follows:

f(x)= 3x+1 if x is less than or equal to 0

2x^2 if 0 4 if c is greater than or equal to 2

determine the following values of the function

f(-3)= __

f(2)= ___

Answer:

The values are
$f(-3)=-8$ and
$f(2)=8$

Step-by-step explanation:

The function is defined by two parts,


$f(x)=3 x+1$ if
x\leq 0


f(x)=2x^2 if
$x \geq 2$

To determine the value of
$f(-3) , we shall substitute the value
x=-3 in the function
$f(x)=3 x+1$ because
$-3 \leq 0$

Hence, we have,


f(x) \ \ =3 x+1\\f(-3)=3(-3)+1\\f(-3)=-9+1\\f(-3)=-8

Now, to determine the value of
f(2) , we shall substitute the value
x=2 in the function
f(x)=2x^2 because
$x \geq 2$

Hence, we have,


f(x)=2 x^(2)\\f(2)=2\left(2^(2)\right)\\f(2)=2(4)\\f(2)=8

Thus, the values are
$f(-3)=-8$ and
$f(2)=8$
