Explanation:
Given function: f(x) = -2x² - 3x + 20
To find the x-intercepts of a function, f(x) = 0
=================
-2x² - 3x + 20 = f(x)
-2x² - 3x + 20 = 0
-2x² - 8x + 5x + 20 = 0
-2x(x + 4) + 5(x + 4) = 0
(-2x + 5) (x + 4) = 0
-2x + 5 = 0, x + 4 = 0
-2x = -5, x = -4
x = -5/-2,x = -4
x = 5/2, x= -4
Coordinates: (-4, 0), (5/2, 0)
Answer:
Fish with -1 foot
Step-by-step explanation:
- = under
+= above
If you set your water level to 0 then:
-1 +0 = -1 so the fish is 1 foot under the water level
-5 +0 = -5 do the fish is 5 foot under the water
And the last fish either jumped super high or it was hanging on a fishing line becouse it was 8 feet above the water level
So the fish that was the closes to the water level was the fish with -1
