The expression given by f(x)=a(x-h)^2+k is a the equation of a vertex where (h,k) is the vertex. The importance of h is that it represents the x-intercept, the lowest or the highest point of the graph of the expression. This is a very important factor when determining the turning points of parabolas
Answer:
True
Step-by-step explanation:
The integral

in the integral we have a product of a monomial: 
and an exponential function: 
In general case, when we have a combination of these two things you can use the integration by parts, where
will be
and
will be
.
The statement is true
( − 5 ) ( + 5 ) ( 2 + 2 5 )
The answer should be 7(x+8)
Answer:
I will assume the equation is supposed to be f(x) = <u>x^2</u> – 5x + 12 since it is said to be a quadratic equation.
Step-by-step explanation:
<u>See attached graph.</u>
The value of f(–10) = 82 <u><em>False</em></u>
f(-10) = (-10)^2 - 5*(-10) + 12
f(-10) = (100) +50 + 12
f(-10) = 162
The graph of the function is a parabola. <u><em>True</em></u>
The graph of the function opens down. <u><em>False</em></u>
The graph contains the point (20, –8). <u><em>False</em></u>
The graph contains the point (0, 0). <u><em>False</em></u>
