Question

F(x)=2x-3 find f(-1/4)

Show work

Answer 1

Explanation:

f(-1/4) means that wherever you see an x on the right, you put in -1/4. This is a shorthand for what to do with the x to solve for y. f(x) = y for most but not all properties.

f(-1/4) = 2(-1/4) - 4

f(-1/4) = -1/2 - 4

f(-1/4) = - 4 1/2 or

f(-1/4) = -4.5
