Key Points Quadratic

Label the following important points on the graph.

Select the x-intercepts of the graph.

Select the vertex of the graph.

Select the y-intercept of the graph.

Which answer choice describes  y = -3x² +7x - 2 accurately?

Which of the following represents a quadratic function?

Quadratic functions $$g\left(x\right)$$ & $$k\left(x\right)$$ are shown below:

$$g\left(x\right)=5x^2-12$$

$$k\left(x\right)=5x^2+c$$

What value of c will the graph of $$k\left(x\right)$$ be 9 units above the graph of $$g\left(x\right)$$ ?

(a)  

Match the following term with the best definition.

If the x-value of the vertex is 1, What is the y-value?

$$y=x^2-2x+3$$ ?

Determine if the following are either x-intercepts, y-intercepts, or a vertex.
