Step-by-step explanation:

First, set up a proportion.

=

Then cross-multiply to get your equation.

25 * x = 325 * 2

25x = 650

Finally, isolate the variable to find your answer.

x = 650/25

x = 26 teachers

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
