Linear



Quadratic, f(x) = x2 – 5x - 2



Exponential, Linear, y = 2x + 4, f(x) = 3.47



y = 2x + 4, Exponential



f(x) = x2 – 5x – 2, Linear



f(x) = 3.4"

Answer 1

Answer:

y = 2x + 4

Step-by-step explanation:

The linear functions are the ones that can have at most 1 x-intercept. Specifically, slant lines and vertical lines have this characteristic.

The quadratic function doesn't have this characteristic because there are cases where it intercepts x-axis at two points (concave down).

Additionally, the exponential function doesn't have any x-intercept, because its range is restricted.

Therefore, the right asnwer is the linear function

Answer 2

The function that  could have at most 1 x-intercept is y = 2x + 4.

What is a linear function?

It is the function that can have at most 1 x-intercept. When slant lines and vertical lines should contain the attributes.

The quadratic function doesn't have this attribute since there are cases where it intercepts the x-axis at two points  that represent concave down.

Moreover, the exponential function doesn't have an x-intercept, since its range is restricted.

Therefore, it should be a linear function.
