use the graphing calculator to graph and find the zeros of the function y = 2x2 + 0.4x – 19.2. the zeros of the function are

–3.2 and –19.2.
–3.2 and 3.
–3 and 3.
–3 and –19.2.

zeros are -3.2 and 3

Step-by-step explanation:

Use the graphing calculator to graph and find the zeros of the function

y = 2x^2 + 0.4x – 19.2

WE use graphing calculator to graph the equation y = 2x^2 + 0.4x – 19.2

Then we look at the points where the graph crosses x axis

zeros are the x values that where the graph crosses x axis

At x axis the y values are 0. so to get zeros we look at the x  values where y is 0

the graph is attached below

(-3.2,0)  and (3,0)

zeros are -3.2 and 3

hi there

the slope is 1/3.

this is because from the y-intercept, you go up one, and you go to the right three, to get to the next exact point on the graph. this is known at the “rise over run.”

p.s. (if you need it).your y-intercept is -2, because that is the point on the graph where the line crosses the y-axis.

hope that : )

slope intercept form is y = mx + b
