Answer:
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
