Question

I don't understand would this be a linear function,quadratic function,or exponential function

Answer 1

In the given figure there are 3 graphs

The line represents a linear function

$h(x)=x+2$

The parabola represents a quadratic function

$g(x)=2.5x^2+2x$

The third graph which approaches to the negative part o the x-xis is the exponential function

$f(x)=2^x$

The x-intercept of the line is (-2, 0)

x-intercept means intersect the x-axis at point (-2, 0)

There is only one graph that intersects the x-axis at (-2, 0)

It is the line, the linear function h(x)

The range is between 0 to infinity (0, ∞)

The range is the values of y

There is only one graph that has all values of y over the x-xis

it is f(x) the exponential function
