Hello! My name is Galaxy and I'll help you with your problem today. I hope you are having a nice day!

The Function

First of all, to figure out the function and how it will work, with that, we can see that it is a parabola, a parabola is a function which looks like a curve in which the multiplication of the $x$ cation, when more smaller, is more wider.

Parabola's also have two ways they go, them being upwards and downwards which in the quadratic formula are figured out by the a catition.

$ax^2+bx+c=0$

Solving

So, we know to find for $f(1)$ we have to find what is y when x is 1. To solve for that, we can look at the function's graph and see that when x is one, y is 5.

Solution

To solve for this, we can usually just look at the graph to see where the point where we need to find is, but, we also might have to graph the equation if the graph is not already given.

So our answer would be $y=5$ and/or $(1,5)$

Cheers!

Answer 2

The answer is 5.
Because take x=1 entry to the graph and going vertical until you intercept the curve, then read the value on the y axial
