I need help understanding this

f(0) = 1

Step-by-step explanation:

you are given a graph of the function f  

If we describe this in words, we can say that we are given a graph of f(x)  where "x" is the value of the graph on the x-axis and f(x) is the corresponding value of y on the graph

in this case, we are asked to find f(0). If we compare f(0) with our explanation of f(x) above, we can conclude that we are asked to find the value for y (on the graph) when x = 0.

Simply reading from the graph, we can see that when x = 0, the corresponding value of y on the graph is 1  (i.e the vertex of the graph).

hence f(0) = 1

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
