Given f (x) = 10 minus 2 x, find f(7).
–4
3
7
56

f(7) = -4

Step-by-step explanation:

f (x) = 10 - 2 x

Let x = 7

f(7) = 10 -2(7)

     = 10 -14

    = -4

Put 7 in place of x 10-2(7)= 10-14= negative 4

Therefore, the answer is A. -4.

Hope this helps! :)

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
