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

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.

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
