When you evaluate the function f (x) = 4 • 7 ^ x for x = -1 you get:
f (-1) = 4 * 7 ^ -1
f(-1) = 4* 1/7
f (-1) = 0.5714
The next part of the question is not clear. If it refers to the function at x = 2 then:
f (2) = 4 * 7 ^ (2)
f(2) =4*49
f (2) = 196
If it refers to it in x ^ 2
f (x ^ 2) = 4 * 7 ^ (x ^ 2)
Can you give the options? sorry If I know the options I will tell you in the comments!!
7 over 4x-3 you just flip the fraction to get the inverse
Answer: 9 so the fraction would be 9/24
(15,-10) (17,2)
(2+10)/(17-15)= 12/2 = 6
The slope is 6
