Answer:
26
Step-by-step explanation:
3x^2 + 7x
when x = 2,
=> 3(2)^2 + 7(2)
=> 3(4) + 14
=> 12 + 14
=> 26

Answer: y = 2/5 x + 2
Step-by-step explanation:
why not do this one too yk
slope = y2 - y1 / x2 - x1
4 - 2 / 5 - 0
slope = 2/5
ill use (5,4) for the y=mx+b initial equation
y = mx+b
4 = (2/5)(5) +b
4 = 2 + b
2 = b
now for the final equation whoop whoop
y = 2/5 x + 2
What are the number or what is the equation.What amount of dollars
Let A( t , f( t ) ) be the point(s) at which the graph of the function has a horizontal tangent => f ' ( t ) = 0.
But, f ' ( x ) = [ ( x^2 ) ' * ( x - 1 ) - ( x^2 ) * ( x - 1 )' ] / ( x - 1 )^2 =>
f ' ( x ) = [ 2x( x - 1 ) - ( x^2 ) * 1 ] / ( x - 1 )^2 => f ' ( x ) = ( x^2 - 2x ) / ( x - 1 )^2;
f ' ( t ) = 0 <=> t^2 - 2t = 0 <=> t * ( t - 2 ) = 0 <=> t = 0 or t = 2 => f ( 0 ) = 0; f ( 2 ) = 4 => A 1 ( 0 , 0 ) and A 2 ( 2 , 4 ).
