Answer:

is the LAsT one because 5x-1 can t be 0 so x doesn t have to be equal to 1/5 which would make 5x-1 =0.

Find the minimum value of the function f(x)=x^2+5x-6

mash [69]

<h3><u>Explanation</u></h3>

Method 1 (Formula)

$\begin{cases}h = - \frac{b}{2a} \\ k = \frac{4ac - {b}^{2} }{2a} \end{cases}$

The vertex of Parabola is the maximum/minimum point depending on the value of a.

Find Vertex

<u>h-value</u>

$h = - \frac{5}{2(1)} \\ h = - \frac{5}{2}$

<u>k-value</u>

$k = \frac{4(1)( - 6) - {(5)}^{2} }{4(1)} \\ k = \frac{ - 24 - 25}{4} \\ k = \frac{ - 49}{4} \\ k = - \frac{49}{4}$

The minimum value is the value of k. Therefore the minimum value is - 49/4 at x = -5/2.

Method 2 (Derivative)

This is Calculus method. We simply differentiate the function then substitute y' = 0.

Differentiate Function

$f'(x) = 2 {x}^{2 - 1} + {5x}^{1 - 1} - 0 \\ f'(x) = 2x + 5$

Substitute f'(x) = 0

$0 = 2x + 5 \\ - 5 = 2x \\ - \frac{5}{2} = x$

Substitute x = -5/2 in the original equation.

$f(x) = {( - \frac{5}{2} )}^{2} + 5( - \frac{5}{2} ) - 6 \\ f(x) = \frac{25}{4} - \frac{25}{2} - 6 \\ f(x) = \frac{25}{4} - \frac{50}{4} - \frac{24}{4} \\ f(x) = \frac{25}{4} - \frac{74}{4} \\ f(x) = - \frac{49}{4}$

<h3><u>Answer</u><u /></h3>

<u> $\sf{the \: \: minimum \: \: value \: \: is \: \: - \frac{49}{4} \: \: at \: \: x = - \frac{5}{2} }$ </u>

Plz HELP ME

TiliK225 [7]

remember that you have to do the same to both sides

$\frac{x}{4}+16>34$

minus 16 both sides

$\frac{x}{4}+16-16>34-16$

$\frac{x}{4}+0>18$

$\frac{x}{4}>18$

mulitply both sides by 4

$\frac{4x}{4}>18*4$

$(x)(\frac{4]{4})>72$

$(x)(1)>72$

$x>72$

Help please! quadratic equation and stretch factor

Goshia [24]

Answer:

Equation: f(x)=x²-4x+3

Stretch factor: a=1

Step-by-step explanation:

Notice the x-intercepts are (1,0) and (3,0) which can help us determine the equation by setting their expressions equal to 0 and expanding:

(x-1)(x-3)=0

x²-4x+3=0

Therefore, the equation is f(x)=x²-4x+3 where the stretch factor is a=1
