Answer:

-1, 4

Step-by-step explanation:

log_2x+ log_2(x-3)=2 \\ log_2 \{x(x-3) \}=2  \\ x(x - 3) =  {2}^{2}  \\  {x}^{2}  - 3x = 4 \\  {x}^{2}  - 3x - 4 = 0 \\  {x}^{2}  - 4x + x - 4 = 0 \\ x(x - 4) + 1(x - 4) = 0 \\ (x - 4)(x + 1) = 0 \\ x - 4 = 0 \:  \: or \:  \: x + 1 = 0 \\  x = 4 \:  \: or \:  \: x =  - 1 \\  \huge \red{ \boxed{x =  \{ - 1, \:  \: 4 \}}}

F(x)=20-x^2+8x<br> what are the minimum and maximum points and the axis of symmetry?
-Dominant- [34]
Vertex aka max or min point is found by -b/2a in form
f(x)=ax^2+bx+c
f(x)=-1x^2+8x+20
vertex x value is -8/(2)(-1)=-8/-2=4
input back to find y value
f(4)=-(4^2)+8*4+20
f(4)=-16+32+20
f(4)=36
max (since the graph opens down) is (4,36)
axis of symmetry is the x coordinate


max is (4,36)
axis of symmetrry is x=4
