Answer:

y=-4x^2+9x+9

Step-by-step explanation:

1st: we assume the equation will be in standard form (ax^2+bx+c)

2nd: since the graph passes through (0,9) then the y-intercept is @(0,9) or your c is 9.

3rd: since it passes through (2,11) then 11=4a+2b+c

4th: since it also passes through (3,0) then 0=9a+3b+c

* so we have c=9, 11= 4a+2b+c, and 0= 9a+3b+c*

So a=-4, b=9, c=9

plug in the numbers and you get y= 4x^2+9x+9

Hope this helps you. :3

Evaluate the function for x = 2,3,4<br> F(x) =2x-7-3

laila [671]

Answer:

below in bold

Step-by-step explanation:

f(x) = 2x - 7 - 3

~Combine like terms

f(x) = 2x - 10

When x = 2...

f(x) = 2(2) - 10

f(x) = 4 - 10

f(x) = -6

When x = 3...

f(x) = 2(3) - 10

f(x) = 6 - 10

f(x) = -4

When x = 4...

f(x) = 2(4) - 10

f(x) = 8 - 10

f(x) = -2

Best of Luck!

A. The slope of the curve y=x^3- 1 at the point P(1,0) is<br> .

Ierofanga [76]

Answer:

Step-by-step explanation:

The measure of the slope is $\frac{dy}{dx}$ at x = a

Differentiate using the power rule

$\frac{d}{dx}$ (a $x^{n}$ ) = na $x^{n-1}$

Given

y = x³ - 1, then

$\frac{dy}{dx}$ = 3x²

The slope at (1, 0) is

$\frac{dy}{dx}$ = 3(1)² = 3
