Answer:

\dfrac{f(x+h) - f(x)}{h}=-8x-4h-3

Step-by-step explanation:

f(x)=-4x^2-3x-4

f(x+h)=-4(x+h)^2-3(x+h)-4

f(x+h)=-4(x^2+2xh+h^2)-3(x+h)−4

f(x+h)=-4x^2-8xh-4h^2-3x-3h-4

f(x+h) - f(x)=-4x^2-8xh-4h^2-3x-3h-4-(-4x2-3x-4)

f(x+h) - f(x)=-4x^2-8xh-4h^2-3x-3h-4+4x2+3x+4

f(x+h) - f(x)=-8xh-4h^2-3h

f(x+h) - f(x)=h(-8x-4h-3)

\dfrac{f(x+h) - f(x)}{h}=\dfrac{h(-8x-4h-3)}{h}

\dfrac{f(x+h) - f(x)}{h}=-8x-4h-3

What division statements have a quotient of 20
Jlenok [28]

Answer:

In the example, 20 is the dividend, five is the divisor, and four is the quotient. Unlike the other basic operations, when dividing natural numbers there is sometimes a remainder that will not go evenly into the dividend; for example, 10 ÷ 3 leaves a remainder of one, as 10 is not a multiple of three.

Find the value(s) of "k" that will cause the equation 4x^2 +kx + 4 to have one real solution.
Andreas93 [3]

Answer:  k = {8, -8}

<u>Step-by-step explanation:</u>

In order for a quadratic equation to have exactly one solution, the discriminant must equal zero.       →        b² - 4ac = 0

  4x² + kx + 4 = 0

  ↓       ↓      ↓

a=4    b=k    c=4

b² - 4ac = 0

k² - 4(4)(4) = 0

k²             = 64

           k = √64

           k = ± 8

50 POINTS please help me I really need it
Mars2501 [29]

A Domain is the lowest and highest x value (-5,-2) is how it is formatted this means -5 to -2

Range is the lowest to highest Y value so (-3,3)

(-5,-2) - domain

(-3,3) - range

B Intercept are when the line crosses the acis labeled x so

(-2,0) and (2,0)

C F(1) means what is x when y is equal to 1 so we must estimate this

(-1,1) and (1.5,1)

D f(x) = -3 is when y is -3 so we look at the graph to see

-5 and 4 are the values for x

E f(x) < 0 means when y is above the x axis

This is between the x values of -2 and 2 or (-2,2)
