Hi, Currently working on revision for an upcoming algebra class and I just want to make sure I did these problems correctly. Let me know where I went wrong if I did!
The problem asks If f(x) = 4x^2 − x + 4, find the following.
f(a + 1) = 4a^2+7a+7
2f(a) =2(2a^2-a+4)
f(2a) = 4(a^2-a+1)
[f(a)]2 = 4(a^2)^2 - (a^2) + 4
f(a+h) = 4(a+h)^2 - (a+h) +4
]Let me know what you think!
