Answer:
- If x=0 , then f(0)=2
- If f(x)=0 , then x = -1
Step-by-step explanation:
First lets assume that the y axis is called the<em> ordinate axis </em>and the x axis is the <em>abscissa axis</em>
Then:
- The first question asks for the y value in the <em>ordinate axi</em>s that corresponds to the x = 0 value. To begin:
You must start to locate the x=0 value on the abscissa axis, its located in the center of the axis.
Then you start for searching the y value that the curve takes when it passes through the ordinate axis, this correspond to the value of the function f(x) on x=0. The value according to the graph is y=2.
Then , you located the point (0,f(0))=(0,2).
- The second question asks for the x value in the abscissa axis that corresponds to the f(x)=y=0 value. To begin this, you start the other way around:
You must locate the y=0 value on the ordinate axis, its also located in the center of the axis.
Then you start for searching the x value that the function needs to take the y=0 value. According to the graph the value of x that the function needs is x = -1
Then, you located the point where f(x)=y=0, its (-1,0).
