f(x) = x²
The vertex form of a quadratic equation is: f(x) = a(x - h)² + k where;|a| is the vertical stretch-a is a reflection across the x-axis(h, k) is the vertex
The parent function is where a = 1 and the vertex is at the origin (h, k) = (0, 0)
→ f(x) = 1(x - 0)² + 0
⇒ f(x) = x²
b is 38 degrees.
a is 52 degrees.
this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
options a,b,c are the right answer.
a linear parent function is always represented as y = x
if we write this function in the form of y=mx+c
now if we plot a graph we will find these characteristics:
1) y intercept of the graph is zero so its a straight line passing through origin.
2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.
3) it's slope is one.
