Mathematics
1 answer:
nexus9112 [7]3 years ago
6 0

Answer:

Step-by-step explanation:

y = x² + x - 3

x = - 3

y = ( - 3 )² + ( - 3 ) - 3 = 3

( - 3 , <em>3</em> )

x = 0 ⇒ y = - 3

( 0 , <em>- 3</em> )

x = 1

y = ( 1 )² + ( 1 ) - 3 = - 1  

( 1 , <em>- 1 </em>)

<em>(b).</em> Coordinate x of the vertex of quadratic equation y = ax² + bx + c is

- \frac{b}{2a}

x = - \frac{1}{2(1)} = - \frac{1}{2} = - 0.5

y = ( - 0.5 )² + ( - 0.5 ) - 3 = - 3.25 = - 3\frac{1}{4}

( - \frac{1}{2} , - 3\frac{1}{4} )

If f(x)=x^3-x what is the average rate of change of f(x) over the interval [1, 5]?
Serjik [45]
Average rate of change= [f (x2)-f (x1)]/(x2-x1)
(the same formula of the slope)
x2=5
x1=1
f (x2)=5^3-1 =124
f (x1)= 1^3-1 =0
(124-0)/(5-1) = 31
