Step-by-step explanation:
4-17x^2+16=0 s
Calculate multiply
20-17x^2=0
Reoder the term
-17x^2+20=0
Calculate the discriminat
D=0^2-4x(-17)x20
Simplify
D=1360
The quadric equation has 2 real solutions
So your Solution is :
2 real solutions
Answer:
C
Step-by-step explanation:
Plug 1, 2, and 3 into n and you'll get 15, 13, and 11 respectively
Answer:
Example Question: f(x) = 2x^2 + 2x - 1
If the leading coefficient is positive, the graph will be opening up (U) if the leading coefficient is negative, the graph will be opening down (n)
Roots are the x-intercepts that help find the axis of symmetry (add the two roots together and divide the result by 2 to get the axis of symmetry)
To find the vertex, simply imput the axis of symmetry into the given equation.
And that’s about it.
Step-by-step explanation:
I don’t know what you’re asking for??
The answer is B :)
