Two construction companies, Big Time Builders and Goldstar Construction, are building tunnels for a city. It takes Big Time Builders 4 weeks to build 84 meters of tunnel. This equation describes how fast Goldstar Construction builds tunnels, where y represents the length of tunnel it builds in meters and x represents the number of weeks it takes.

all it means is function 3

x + 4/7

step-by-step explanation:

use cymath

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

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
