For all functions of the form f(x) = ax^2 + bx + c, which is true when b=0
1 answer:
Answer:
The y-intercept will always be the vertex of the function.
Step-by-step explanation:
The functions with the following form are quadratic equations and have a parabolic form, which means the have a vertex. The x coordinate of the vertex is given by the following expression
. When b is equal to zero, the vertex of the function will always be the y-intercept, therefore the correct answer is the third one.

Answer:
122°
Step-by-step explanation:
The measure of the central angle is twice the measure of the inscribed angle that subtends the same arc.
∠ABC = 2×∠ADC = 2×61°
∠ABC = 122°
