In a function, there can be a repeated output value b. In a function, each input can only have one output c. In a function, the domain is the set of all output values d. In a function, the range is the set of all output values e. In a function, a vertical line can only cross its graph one time f. In a function, the y values represent the independent variable g. In a function, the dependent variable is the y variable h. In a function, there can be repeated input values with different outputs

the answer is d

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

answer: 1+1

step-by-step explanation: 1+1 is at least 2
