The answer to your question is 4x^2+11x-20
Answer:
f(4)=2(x)^2-5(4)+4
Step-by-step explanation:
f(x) is basically just y, but it is also telling you what the value of x is. So if f(4) then that means that x is 4, so you can just replace x with 4 and simplify. Hope this helps :)

You can do this by taking away the second equation from the first to get rid of the x terms so:
7x - 7x = 0
-5y - -9y = - 5y + 9y = 4y
22-6 = 16
So you are left with the equation:
4y = 16
Divide both sides by 4 to find y
y = 4
