A function, f(x), represents the distance a car travels over time. The line tangent to the function at x=1 is y=0.6x+0.9. The li
ne tangent to the function at x=4 is y=2.1x-3.2. The line tangent to the function at x=6 is y=4.6x-16.3.

Answer:
0.6
Step-by-step explanation:
The instantaneous rate of change at any point on a curve is the slope of the tangent line at that point.
At x=1, the tangent line is given as ...
y = 0.6x +0.9
The slope of that line is the coefficient of x, 0.6.
The instantaneous rate of change of f(x) at x=1 is 0.6.
