Question

suppose f(x)=2x-5 and g(x)=1-3x-1
find f (-1)-g(3)
show all steps

Answer 1

To find f(-1), we substitute -1 into the function f(x):

f(-1) = 2(-1) - 5
f(-1) = -2 - 5
f(-1) = -7

To find g(3), we substitute 3 into the function g(x):

g(3) = 1 - 3(3) - 1
g(3) = 1 - 9 - 1
g(3) = -9

Finally, we can find f(-1) - g(3) by subtracting the values we found:

f(-1) - g(3) = -7 - (-9)
f(-1) - g(3) = -7 + 9
f(-1) - g(3) = 2

Therefore, f(-1) - g(3) = 2.
