Answer:
7
Step-by-step explanation:
Explanation of
f(x) = 2x + 1 for x ≥ 3
f(x) = 3x - 3 for x < 3
when the x in f (x) is greater than or equal to 3 we use the equation 2x + 1
When the x in f (x) is less than 3 we use the equation 3x - 3
we want to find f ( 3 )
because x is greater equal to 3 we use the equation 2x + 1
so to find f ( 3 ) we simply plug in the value of x into the equation
f ( 3 ) = 2(3) + 1
multiply
f ( 3 ) = 6 + 1
add
f ( 3 ) = 7
