F(x)=x^2-3x; Find f(-8)

Bumek [7]

F(x) = x^2 - 3x
f(-8) = (-8)^2 - 3(-8)
f(-8) = 16 - (-24)
f(-8) = 16 + 24
f(-8) = 40 (Answer)

Consider the graph shown.

Butoxors [25]

Answer:

$Slope=\frac{3}{4}$

The equation of line is $y=\frac{3}{4}x+1$ .

Step-by-step explanation:

If a line passes through two points $(x_1,y_1)$ and $(x_2,y_2)$ , then the slope of the line is

$m=\frac{y_2-y_1}{x_2-x_1}$

From the given graph it is clear that the line is passes through the points (0,1) and (4,4).

$Slope=\frac{4-1}{4-0}$

$Slope=\frac{3}{4}$

The

The slope intercept form of a line is

$y=mx+b$

where, m is slope and b is y-intercept

The slope of the line is $\frac{3}{4}$ and y-intercept is 1, so the equation of line is

$y=\frac{3}{4}x+1$

Therefore, the equation of line is $y=\frac{3}{4}x+1$ .

notka56 [123]

Step-by-step explanation:

Using distance formula,

Let the distance between point E and F = ef,

$ef = \sqrt{{(7 - 1)}^{2} + {(2 - 9)}^{2} } \\ ef = \sqrt{85} \\ = 9.219544457$
