Please help I it’s easy but not for me :)

QB)F(x)= -2x +3

A)step 1)

To find x intercept/zero,substitute f(x)=0,

so 0=2x +3

step 2)Move the variables to the left hand side and change it's sign,

2x+3

step 3)Divide both sides

x=3/2

Alternate form:

x=1 1/2,x=1.5

QA) f(x) 2x + 3

step 1) Find the x -intercept/zero,substitute F(x) =0,

0=2x+3

step 2)Move the variable to the left hand side and change its sign

-2x=3

step 3)Divide both sides of the equation by -2,

x= -3/2

Almternate form:

x= -1 1/2,x =1 .5

QC)f(x)=2x-6

step 1)Find the x -intercept/zero,substitute F(x) =0,

0=2x - 6

step 2)Move the variable to the left hand side and change its sign

-2x= -6

step 3)Divide both sides of the equation by -2,

-2x= -6

x= 3

QD)F(x)= - 2x -6

step 1)Find the x -intercept/zero,substitute F(x) =0,

0= -2x-6

step 2)Move the variable to the left hand side and change its sign,

0= -2x - 6

2x=6

step 3)Divide both sides of the equation by 2,

2x= -6,

x= -3

3 is greater then both of those numbers
