Answer:
part A: The x-intercept of the graph is the point where the function crosses the x-axis. for f(x)=2x2-5x+3 its (1,0)
part B= If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value. In either case, the vertex is a turning point on the graph.

Step-by-step explanation:
Given the expression

We know that the domain of a function is the set of inputs or argument values for which the function is real and defined.
We know that we can not have a negative value of 't' inside the radicals because if we put any negative number inside the radical expression, it would make the function undefined.
In other words, the value of t ≥ 0.
Therefore, the function domain is:

Answer:
c=27/40
in decimal form 0.675
Step-by-step explanation:
1/8+c=4/5
c=4/5
-1/8
c=27/40
The answer is b.
when x decreases, f(x) decreases.
when x increases, f(x) increases.
