The function f(x) = − x^2+ bx +1 is shown in the graph. What is the value of b?
denis-greek [22]

Answer:

b = 4

Step-by-step explanation:

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

here ( h, k ) = (2, 5 ) , then

y = a(x - 2)² + 5

to find a substitute any point on the parabola into the equation

using (0, 1 ) then

1 = a(0 - 2)² + 5 ( subtract 5 from both sides )

- 4= a(- 2)²= 4a ( divide both sides by 4 )

- 1 = a

then

y = - ( x - 2)² + 5

   = - (x² - 4x + 4) + 5

    = - x² + 4x - 4 + 5

    = - x² + 4x + 1 ← in the form ax² + bx + c

with b = 4

A video store charges the same fee each day a video is returned late. Craig returned a video 4 days late and paid a $3 fee. Writ
vova2212 [387]

Answer:

$5.25 if returned 7 days late

Step-by-step explanation:

So we know that 4 days late is 3 dollars

We can find the unit rate

3/4 is 0.75

So 75 cents for every late day

Now we just multiply that by 7

0.75*7=5.25

so 7 days, 5.25

**porportional relationship equation**

\frac{3dollars}{4 days}=\frac{X}{7 days}

Now cross multiply

21=4x

x=5.25

Same results
