Chelsea is graphing the function f(x) = 20(One-fourth)x. She begins by plotting the initial value. Which graph represents her first step?
On a coordinate plane, the point (0, 0.25) is graphed.
On a coordinate plane, the point (0.25, 0) is graphed.
On a coordinate plane, the point (0, 20) is graphed.
On a coordinate plane, the point (20, 0) is graphed.
On a coordinate plane, the point (0,20) is graphed.
Here’s why: You can rewrite the equation as y=1/4x+20 and 20 is an y-intercept point and the coordinate is (0, 20) Remember that the coordinates are written (x,y).
