I am positive it's correcf
when multiplying two binomials together we use the F.O.I.L. method:
First
Outer
Inner
Last
(7-3i)(2-i)
First: 7 * 2 ..... Outter: 7 * -i .... Inner: -3i * 2 ...... Last: -3i * -i
First: 14 ...... Outter= -7i ..... Inner: -6i .... Last: 3i^2
putting this together we get 14-7i-6i+2i^2
We combine like terms and end up with 2i^2-13i+14

Answer:
When the input is 4, the output of f(x) = x + 21 is 25.
Step-by-step explanation:
The given function is
Here, x is input and f(x) is output.
We need to find the output of the given function f(x) if the input is 4.
Substitute x=4 in the given function.
So, the output value is 25.
When the input is 4, the output of f(x) = x + 21 is 25.
