If graphed on the same grid, the diagrammatic representation of the parabola gives an upward curve.
<h3>What is the graph of a function?</h3>
The graph of the function is a diagrammatic representation of the slope, x-intercept, and y-intercept of the given function.
From the information given:
y = 2.5x²
Here,
- The domain of the given function varies from -∞ to +∞.
- The range is the value of x greater than or equation to 0
x-intercept = (0,0)
y-intercept = (0,0)
Therefore, if graphed on the same grid, the diagrammatic representation of the parabola gives an upward curve.

Answer:
Step-by-step explanation:
Step 1: Factor left side of equation.
(c+1)(c+9)=0
Step 2: Set factors equal to 0.
c+1=0 or c+9=0
c=−1 or c=−9
C= -1 OR C= -9
Use the formula d = rt
where d is the distance
r is the rate
t is the time
when you go pier A to B with the current of 2.5 mph
D = (r + 2.5) 2
D = 2r + 5
when you go back
D = ( r - 2.5) 6
D = 6 r - 15
so 2r + 5 = 6r - 15
r = 5 mph
d = 2r + 5
d = 2(5) + 5
d = 15 miles
