Hack
for y=ax^2+bx+c
the xvalue of the vertex is -b/2a
and the y value is found by subsituting that for x
so
-b/2a
h(t)=2x^2+4x+7
a=2
b=4
-b/2a=-4/(2*2)=-4/4=-1
the y value
h(-1)=2(-1)^2+4(-1)+7
h(-1)=2(1)-4+7
h(1)=2+3
h(1)=5
(-1,5) is da vertex
Answer:
Good Morning my favorite is Attack on Titan.
Step-by-step explanation:
Answer:
Neither
Step-by-step explanation:
After substituting the ordered pair into the equation, none of the pairs satisfy the equation
because 6(3)+3(-2)=12 and 6(2)+3(2)=18.
Answer:
d.
Step-by-step explanation:
The red graph is the black one times 2.
So y = 2 f(x). which is the same as y/2 = f(x) (divide by 2).
