Answer:

x-ints: (2,0) & (4,0)

y-int: (0,-8)

vertex: (3,1) *highest point of the graph

line of symmetry: x = 3 *x-value in the middle of x-ints

a value is -# *if parabola points done it's negative, if it points up it's positive

Use the function f(x) = 2x3 - 3x2 + 7 to complete the exercises.

GenaCL600 [577]

Easy
sub 2 for x

f(2)=2(2)^3-3(2)^2+7
f(2)=2(8)-3(4)+7
f(2)=16-12+7
f(2)=11

How do you find out if a like is parallel, perpendicular, or coincidental when theres 2 equations

finlep [7]

The slope intercept form of the equation of a line is given as:

y = mx + c

where m = the slope of the line

c = the y - intercept of the line

1) Two line are parallel if they have the same slope

That is:

$\begin{gathered} \text{If the equation for line 1 is: y = m}_1x+c_1 \\ \text{If the equation for line 2 is: y = m}_2x+c_2 \\ \text{Then, line 1 is parallel to line 2 if m}_1=m_2 \end{gathered}$

2) Two equations are perpendicular if the slope of one is the negative inverse of the other.

$\text{That is : m}_1=\text{ }\frac{-1}{m_2}$

3) Two equations are coincidental if they have the same slope and the same y intercept

$\begin{gathered} \text{That is: m}_1=m_2_{} \\ \text{and c}_1=c_2 \end{gathered}$

seraphim [82]

$1\ ft=12\ in\to3\ ft=3(12\ in)=36\ in\\\\3\ ft:18\ in=36\ in:18\ in=36:18=\dfrac{36}{18}=\dfrac{2}{1}=2:1\\\\Answer:\ \boxed{3\ ft:18\ in=2:1}$
