Use f(x) = 2x -3 to find the following: f(-2)

-7

Step-by-step explanation:

Substitute the value of -2 into all of the x-values

f(-2) = 2x-3

       = 2(-2) -3

       = -7

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
