Sketch the graph of y=-4(x+4)^2+4 and identify the axis of symmetry.​

(-4,4) is the vertex.  The graph is symmetrical to the x = -4 line.

Step-by-step explanation:

Graph the equation using DESMOS.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
