Answer:
4)x=2
5) (-3,4)
Step-by-step explanation:
4) f(x)=x^2-4x+4-4+5
f(x)=(x-2)^2+1
f(x)=a(x-h)^2+k
Axis of symmetry is x=h
h is 2, so axis of symmetry is x=2
5) f(x)=x^2+6x+9-9+13
f(x)=(x+3)^2+4
f(x)=a(x-h)^2+k
Vertex is (h,k)
So, vertex is (-3,4)
Sorry, I can't answer the first 3, cause I don't understand what a-value, b-value and c-value mean.
And also is this college math, cause I'm in middle-school, and I know how to do it.
The area of a triangle is 1/2*base*height so 1/2*10*8 which is equal to 40in²
So you should label the x axis and y axis like I did then you use the formula!
