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 :)
f(x) find f(-4)
just plug in all f(x) for f(-4)
I'll get u started. 2(-4)^2-5(-4)+4
2(16)+20+4
32+20+4
56
Hope this helps plz hit the crown ;D
