Question

Determine f(3) for A piecewise function f of x in three pieces. The function is defined by part 1, which is x cubed for x less than negative 4, part 2, which is 2 times x squared minus 9 for negative 4 is less than or equal to x which is less than 3, and part 3 which is 5 times x plus 4, for x greater than or equal to 3..

what it looks like :

Answer 1

$f(3)=5\cdot3+4=19$

Answer 2

A function assigns the value of each element of one set to the other specific element of another set. The value of the function when the value of x is 3 is 19.

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

As the value of the fucntion is nmeeded to be gound when the value of x is 3, therefore, we can write the function as,

f(3) = 5x + 4 {Becasuse, the value of x is 3}

f(3) = 5(3) + 4

f(3) = 19
