A car's speedometer has a percent error of 5%. The actual speed of the car is 60 mph. Which statement describes what speed the speedometer could show?
o The speedometer shows either 30 mph or 90 mph.
o The speedometer shows either 55 mph or 65 mph.
O The speedometer shows either 57 mph or 63 mph.
o The speedometer shows either 58 mph or 62 mph.

-14 is the answer

hope this : ))

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
