which quadratic function is represented by the table?
a f(x) = 3x^2 + 2x – 5
b f(x) = 3x^2 – 2x + 5
c f(x) = 2x^2 + 3x – 5
d f(x) = 2x^2 – 2x + 5

f(x) = 3x² – 2x + 5.

Step-by-step explanation:

Given : Table with x and f(x).

To find : Which quadratic function is represented by the table.

Solution : We have given that

We need to plug different values of x in f(x).

For x = -2.

f(x) = 3x² – 2x + 5

f(-2) = 3(-2)² – 2(-2) + 5.

f(-2) = 12 + 4 + 5.

f(-2) = 21.

f(-1) = 3(-1)² – 2(-1) + 5.

f(-1)   = 3 + 2+ 5.

f(-1)   = 10.

Therefore, f(x) = 3x² – 2x + 5.

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..
