Just substitute the values in.
if f (x)=-3x+1

a.) f (1)=-3(1)+1
solve.
-3(1)=-3+1=-2

b.) f(-2)=-3(-2)+1
-3(-2)=6+1=7

A. f(1) = -3(1)+1
= -3+1
= -2

b. f(-2) = -3(-2)+1
= 6+1
=7
for this question you just plug in the number given for x in the place of x in the equation and then you solve it as you usually do.

The length of the red line segment is 8 and the length of the blue line segment is 4. How long is the major axis of the eclipse?

liraira [26]

The major axis of the eclipse is 12 units long

The given parameters can be represented as:

$Red = 8$

$Blue = 4$

See attachment for illustration

To solve this question, we make use of the following theorem

The distance between a point and the foci sums up to the major axis

This translates to:

$Major\ axis = Red + Blue$

$Major\ axis = 8 + 4$

$Major\ axis = 12$
