The y-intercept is the value of the function when 'x' is zero. That is, it's the point at which the graph of the function intercepts (crosses) the y-axis. The x-intercept is the value of 'x' that makes the value of the function zero. That is, it's the point at which 'y' is zero, and the graph of the function intercepts the x-axis.
The function y = -1 has no x-intercept; its graph is a horizontal line with a y-intercept of -1.
It can be casually called the x intercept, but it/they is/are the root(s) of the function represented by the graph
No, the graph of a polynomial function cannot have no y-intercept. A polynomial function is defined for all real numbers, and when you evaluate it at (x = 0), you get the y-intercept, which is the value of the function at that point. Thus, every polynomial function will intersect the y-axis at least once, ensuring it has a y-intercept.
The trend of an exponential graph depends on the base of the exponential function. If the base is greater than one (e.g., (y = a \cdot b^x) with (b > 1)), the graph shows exponential growth, rising steeply as (x) increases. Conversely, if the base is between zero and one (e.g., (y = a \cdot b^x) with (0 < b < 1)), the graph depicts exponential decay, decreasing rapidly as (x) increases. In both cases, the graph approaches the x-axis asymptotically but never touches it.
An exponential function is a nonlinear function in the form y=ab^x, where a isn't equal to zero. In a table, consecutive output values have a common ratio. a is the y-intercept of the exponential function and b is the rate of growth/decay.
The point at which a function crosses the x-axis.
The y-intercept is the value of the function when 'x' is zero. That is, it's the point at which the graph of the function intercepts (crosses) the y-axis.

The graph of an exponential function f(x) = bx approaches, but does not cross the x-axis. The x-axis is a horizontal asymptote.
It is an exponential function.
An x-intercept is the point where a function intersects the x-axis on a Cartesian coordinate plane. For example, if the graph of a parabola is plotted and the graph intersects the x-axis on the coordinate plane, the point(s) where the graph intersects the x-axis are the x-intercepts for that function.
An exponential function is of the form y = a^x, where a is a constant. The inverse of this is x = a^y --> y = ln(x)/ln(a), where ln() means the natural log.
Depending on the graph, for a quadratic function the salient features are: X- intercept, Y-intercept and the turning point.

The x- and y-intercepts of a function are the points at which the graph of the function crosses respectively the x- and y-axis (ie. y=0 and x=0).
