f(x) = -x + 5.
This is a vertical parabola open downward
The vertex is a maximum
The equation of a vertical parabola in vertex form is equal to
a is a coefficient
(h,k) is the vertex
In this problem
(h,k)=(0,5) ----> vertex.
The y-intercept is the point (0,5) ---> value of y when the value of x is equal to zero (is the same point that the vertex).
The x-intercepts are the points (√5,0), (-√5,0) --->values of x.
Step-by-step explanation: the line starts from top left between - 8 and -6 and goes through right under 4 / half a square intercepts on the x axis right onto the 4 and to the part stopping between - 8 and -6 once again, so it basically goes diagonal just be sure to make those marks
the awnser is 90 degrees
