Which equation represents the function? f(x)=−1/2x+4 f begin argument x end argument equals negative fraction 1 over 2 end fract
PolarNik [594]

The equation that represents the function is y = -x - 1

<h3>How to determine the equation of the function?</h3>

The complete question is added as an attachment

From the table of values, we have the following points

(x, y) = (-1,0) and (0,-1)

Calculate the slope (m) using

m = (y2 - y1)/(x2 - x1)

Substitute the known values in the above equation

m = (-1 -0)/(0 + 1)

Evaluate the exponent

m = -1

The equation is then calculated as:

y = mx + c

This gives

y = -x + c

Using the point (0,-1), we have:

0 = 1 + c

Solve for c

c = -1

So, we have

y = -x - 1

Hence, the equation that represents the function is y = -x - 1

Her book was 10 days late. D = days. The equation is .25(4) + .30d = 4.00. First you multiply .25 • 4 to get 1. Then you subtract 1 from both sides and get .30d = 3. Next you divide both sides by .30 to get d = 10.
