how do you find the value of a function from a graph at x = -4? trace x = -4 on the x - axis and find the corresponding y value trace x = -4 on the y - axis calculate the area under the curve at x = -4

Answer

Answer:

Trace ( X = -4 ) on the ( X - )axis and find the corresponding ( Y ) value

Explanation:

Step1: Understanding function graphs

A function ( y = f(x) ) has an ( x - )axis (independent variable) and ( y - )axis (dependent variable).

Step2: Locating the value

To find ( f(-4) ), we look for ( x=-4 ) on the ( x - )axis. Then, we move vertically (parallel to the ( y - )axis) until we intersect the graph of the function. The ( y - )coordinate of this intersection point is the value of the function at ( x =-4 ).

For the option “Trace ( X = -4 ) on the ( Y - )axis”: The ( x - )value is located on the ( x - )axis, not the ( y - )axis.

For the option “Calculate the area under the curve at ( X=-4 )”: The area under the curve is related to integration (for continuous functions over an interval), not directly to finding the value of the function at a single point ( x=-4 ).
