Question

Two functions are shown in the table below.


Function 1 2 3 4 5 6
f(x) = −x2 + 4x + 12
g(x) = x + 2


Complete the table on your own paper, then select the value that is a solution to f(x) = g(x).
x = 2
x = 3
x = 5
x = 6

Answer 2

Hi :) no offense but are you almost done replying ?

Answer 3

ok u need to input the given values into the function
eq. f(x)=-x^2+4x+12
so f(1)=-(1)^2+4(1)+12
...
g(x)=x+2
then g(1)=(1)+2
...

Answer 4

f(2)=-2^2+4(2)+12

g(x)=2+2

Answer 5

f(3)=-2^3+4(3)+12

g(x)=3+2

Answer 6

f(4)=-2^4+4(4)+12

g(x)=4+2

Answer 7

u need to solve these...

Answer 8

could you at least help me :(?

Answer 9

ok f(1)=-(1)^2+4(1)+12
=-1+4+12
=15
g(1)=(1)+2
=3

Answer 10

f(2)=-4+8+12
f(2)=4+12
f(2)=12

g(2)=4

Answer 11

f(2)=-(2)^2+4(2)+12
=-(4)+8+12
=16
g(2)= (2)+2
=4

Answer 12

f(3)=-(3)^2+4(3)+12
=-9+12+12
=15
g(3)=3+2
=5

Answer 13

i did f(2) wrong so are we done knee what o i ahebv to do next?

Answer 14

f(4)=-(4)^2+4(4)+12
=-16+16+12
=12
g(4)= 4+2
=6
f(5)= -(5)^2+4(5)+12
= -25+20+12
=7
g(5)= 5+2
=7
f(6)= -(6)^2+4(6)+12
=-36+24+12
=0
g(6)=6+2
=8

Answer 15

f(x)=g(x)
-x^2+4x+12=x+2
-x^2+4x-x+12-2=0
-x^2+3x+10=0
-(x+2)(x-5)=0
x+2=0
x=-2
and x-5=0
x=5
now which option is it?

Answer 16

did u realize that f(5) and g(5) are equal?

Answer 17

yes so x=5 is the option?

Answer 18

correct

Answer 19

ty! could you help with one more??

Answer 20

actually a couple tbh???
