To find the value of a function, substitute the number for the variable and do the arithmetic.

f(x) = -2x^2 +x -5 . . . . . . given

f(3) = -2(3^2) +(3) -5 . . . . function value for x = 3

f(3) = -2(9) +3 -5 = -18 +3 -5

f(3) = -20

What is the equation of the following line written in general form?

strojnjashka [21]

Eq. of line through (1,2) and (4,5) is
$y-y1= \frac{y2-y1}{x2-x1} (x-x1),
y-2= \frac{5-2}{4-1} (x-1)$ $y-2= \frac{3}{3} (x-1)
y-2=x-1
y-2-x+1=0
y-x-1=0$
x-y+1=0

Explain why it is easier to graph an equation in slope intercept form than it is to graph an equation in standard form.

Allisa [31]

In slope intercept form you already have the y-intercept and the slope. all you have to do is plot the y-intercept and then plot the slope from that point.

hope this helps :)
