1) Which is a quadratic function?
f(x) = 2x + x + 3
f(x) = 0x2 – 4x + 7
f(x) = 5x2 – 4x + 5
f(x) = 3x3 + 2x + 2

Answer :

It would have to be c. f(x) = 5x2 - 4x + 5

Answer:

f(x) = 5x² – 4x + 5 is quadratic function.

Step-by-step explanation:

Given : equations .

To find : Which is a quadratic function?

Solution : We have given that equations

We need to find which one is quadratic .

Standard form of quadratic function is f(x) = ax² + bx + c .

We can see from the given option f(x) = 5x² – 4x + 5 .

Here , a = 5 , b = -4 , c= 5

Therefore,  f(x) = 5x² – 4x + 5 is quadratic function.
