At 7 p. m,the temperature was 10 °
f. at 7
a. m, the temperature was -2 °
f. by how much did the temperature change from 7 p. m. to 7
a. m.?

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
