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
The solutions are x = 2.5, y = -1.5, but what are the statements?
hello :
If f(x)=x-2 and g(x)=1/2x,
g(f(x)) = g ( x - 2 )
= 1/2(x-2)
g(f(x)) = (1/2)x - 1
