From the table below, determine whether the data shows an exponential function. Explain why or why not. x: 3 2 1 -1 y: 8 2 0.5 0.125
a.
No; the domain values are at regular intervals and the range values have a common factor 0.25.
b.
No; the domain values are not at regular intervals although the range values have a common factor.
c.
Yes; the domain values are at regular intervals and the range values have a common factor 4.
d.
Yes; the domain values are at regular intervals and the range values have a common factor 0.25.

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

won't that be plagrisim thought?

step-by-step explanation:

c. side angle side. u shares the same sides
