Consider the graph of the quadratic function y=2x-4x+2. How many zeros does the function have?

x=1 ( one solution)

Step-by-step explanation:

y=2x²-4x+2 ( quadratic has to have exponent ( power))

factorize:

2(x-1)^2=0

(x-1)²=0/2

x-1=0

x=1

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
