f(x) has vertex = (- 1, - 5 ) and is a minimum
g(x) has vertex = (2, 3 ) and is a maximum
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
f(x) = (x + 1)² - 5 is in this form with vertex = (- 1, - 5 ) and minimum
to determine if maximum/ minimum
• if a > 0 then minimum
• if a < 0 then maximum
g(x) = - (x - 2)² + 3 is also in vertex form with a < 0
vertex = (2, 3 ) and is a maximum
I could be very wrong, but I believe the answer is C
Circumference of a circle
Answer:
10x^3+13x^2-15x-67
Step-by-step explanation:
First you distribute- 10x^3+25x^2-40-12x^2-15x-27
you distribute the 5 through then the negative 3 through
Then you combine like terms
10x^3+13x^2-15x-67
Then that is just your answer after you add the ones with the squared together and the ones with no variables together
