The expression given by f(x)=a(x-h)^2+k is a the equation of a vertex where (h,k) is the vertex. The importance of h is that it represents the x-intercept, the lowest or the highest point of the graph of the expression. This is a very important factor when determining the turning points of parabolas
(0,4)
The y intercept is the point that is on the line that is going up and down, the y axis, the x axis goes from left to right.
Remember the axis's by this, y is long and tall, so its axis would be going up and down, x is shorter, so its axis would be going left to right
The answer should be the 3rd one
Answer:
about 31.62 units
Step-by-step explanation:
tan(59)=x/19
x=19tan(59)
x=31.62
I think so I don’t know though
