Answer:
Step-by-step explanation:
To find the inverse of a function you take it in y=f(x) form, switch x and y and then solve for the new y.
So I'll do the first one.
f(x) = 8x-10
y=8x-10 Now switch x and y
x = 8y-10 Now solve for y.
x+10=8y
(x+10)/8 = y
g(x) is not that, so it is not the inverse. Can you figure out the second one?
Replace x with the x value solve to get the y value.

Answer:
3/-8
Step-by-step explanation:
Slope= y2-y2/x2-x1
substitute in: 8-5/-7-1= 3/-8
Answer:
Step-by-step explanation:
g(2) = 3(2) + 1 = 6 + 1 = 7
h(7) = 2(7) - 1 = 14 - 1 = 13
Answer:
Step-by-step explanation:
6(1/3X7/5)=(6X1/3)X7/5
6X7/15=6/3X7/5
14/5=14/5 (ASSOCIATIVE LAW)
