Answer:
1
Step-by-step explanation:
This is a function where you have to plug in the value you are given for x. In this case, you are given 1 as your value (after the semicolon). So, you set up your equation like so: (1)^3 + 3(1)^2 -7(1) + 4
(1)^3=1
3(1)^2 = 3
-7(1) = -7
4= 4
so you have 1+3-7+4 which is 1
