What is f(x)= x^2-1 and g(x)=x find (f-g)(-3)

1 answer:

4 0

We calculate f(-3);g(-3) and f(-3) - g(-3);
Then, f(-3) = (-3)^2 - 1 = 9 - 1 = 8; g(-3) = -3; f(-3) - g(-3) = 8 - (-3) = 8 + 3 = 11;

if mr sulivan drove 7hrs within 385 miles and then he drives 3 hrs in the distance of 165 miles is the amount of time of the two

ehidna [41]

the amount of time of the two trips is a proportional relationship

<h3>What is proportional relationship?</h3>

mathematical expressions are said to be proportional if there unit rate are equal. this means that the expressions will give similar results when similar values are substituted into the equation.

<u>solution:</u>

Driving 7 hrs within 385 miles represents a unit rate of 385 / 7 = 55 miles per hour or 55 mph

while 3 hrs in 165 miles represents a unit rate of 165 / 3 = 55 mph

since both situations gave similar speed in miles per hour they are said to have a proportional relationship.
