If you know 84 I’d 70% of the whole, how can you use proportional reasoning to determine the whole

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

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

step-by-step explanation:

graph using a few selected

x         y

-1       15

0         6

1         2.4

2       0.96

answer: 12x^2+6x

step-by-step explanation:

6x does not equal 24x. hope it works!
