Answer:

f'(x)= 2x - 14

Step-by-step explanation:

change f(x) to y   y = 1/2x + 7

switch x and y    x = 1/2y + 7

multiply everything by 2 to cancel the denominator 2x = y + 14

solve for y     2x - 14 = y

then change y to f'(x)   f'(x) = 2x - 14

Practice solving quadratic equations.
Dennis_Churaev [7]
In order for the equation to be true, one of the factors on the left has to equal zero

So, 2x-3=0 or x-4=0 (the 3 on the left for multiplication doesn’t affect the possible answers for x)

Once you solve them, you conclude that x has to be 4 or 3/2.
