Ineed the answer for these. 1a: 1b: 1c:

1a) 8 / (1/2) = 16 * 3 = 48

1b) 3sqrt(49) = 3 * 7 = 21

1c) (5+2)(-8) / (-2)^3 -3

(7*-8) / (-8 -3)

-56/-11

56/11

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
