Answer:
let's see what to do buddy...
Step-by-step explanation:
To find the output of a number in a function, we must put it in the equation of the function instead of the x .
So to find output of ( x = 4 ) , we must put 4 instead of x in the equation .
Let's do it :
[tex]f(4) = 4 \times (4) + 7 \\ \\ f(4) = 16 + 7 = 23 \\ [/tex]
So the output number of ( x = 4 ) is 23 .
