The vertex form of a quadratic function is f(x) = a(x-h)2 + k. What is the vertex of each function? Match the function

rule with the coordinates of its vertex.

(h,k)

Step-by-step explanation:

The vertex of the quadratic function is (h,k), whose standard form is:

i can

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
