Pleaseee helppp I don't understand thissd

Very simple.

Let's say you have an equation.

f(x) = x^2

You are asked to find the value for y when x equals 1.

The new equation is: f(1) = (1)^2

f(1) = 1

When x = 1, y = 1.

The same concept is applied here.

In the graph, where does x equal 0?

It equals zero at the origin.

Is there any y-value associated with 0?

Yes, there is.

Y equals five when x equals 0.

So

h(0) = 5

5

Step-by-step explanation:

Basically the h(0) or whatever number is in the parenthesis just means if h was a certain number, what would the output be?

So in the graph, you have points scattered all over the place. We will take the one right under the -7 on the x axis. That is saying if if h was -7, what will its output be? -7 is the domain or the x value, and the output would be the range or the y value, which in this case is -2. I hope this helps!

answer: finding the extract measurements and knowing the points
