If the function graphed is f(x), find f(1).

Mathematics
1 answer:
Amiraneli [1.4K]3 years ago
3 0

Answer:

f(1)=-4

Step-by-step explanation:

f(1) means what is the y in the point on the curve of f so that x=1.

So I go to x=1 on the x-axis.

So I go right one from the origin.

I notice the curve is below the x-axis so I go down to the curve til I get to the curve.

Once I get to the curve, I look at the y-axis to tell what that number is for that ordered pair there at x=1.

That y-value is -4.

A graph/picture is probably worth a lot more to you then my words.

Other examples:

f(2)=-5

f(3)=0

f(-1)=4

f(-2)=5

f(-3)=0

1. 2(-3) + 4

 -6 + 4 = -2

2. -4^2 - 3

   16 - 3 = 13

3.  2 (m + 2) + 4

   2m + 4 + 4

   2m + 8

   2m = -8

   m = -4

4. i forgot how to do this. sorry :'(

Can someone help me with this
Pavlova-9 [17]

Step-by-step explanation:

after I answered the other one(s), you should be really able to do this yourself.

it is precisely the same method and formula just with different numbers.

what's the problem now ?

y = -16x² + 247x + 141

we assume, the ground is at 0 ft.

so, we need to solve

0 = -16x² + 247 x + 141

the general solution for such quadratic equations is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = -16

b = 247

c = 141

x = (-247 ± sqrt(247² - 4×-16×141))/(2×-16) =

= (-247 ± sqrt(61009 + 9024))/-32 =

= (-247 ± sqrt(70033))/-32

x1 = (-247 + 264.6374879...)/-32 = -0.551171497... s

x2 = (-247 - 264.6374879...)/-32 = 15.9886715... s

again, the negative solution for time did not make any sense, so, x2 is our solution.

the rocket will hit the ground after about 15.99 seconds.
