Answer:
linear
The problem:
[tex]f(x)=\frac{1}{2}x+3[/tex] is linear, quadratic, exponential, or none of these?
Step-by-step explanation:
If the function is [tex]f(x)=\frac{1}{2}x+3[/tex] then f is linear.
It is linear because it is a polynomial with first degree.
It is linear because you can compare it to the slope-intercept form of a linear equation which is y=mx+b. We see thatm=1/2 and b=3.
Example of quadratics:
[tex]a(x)=4x^2+3x+1[/tex]
[tex]b(x)=5x^2+1[/tex]
[tex]c(x)=5x^2-x[/tex]
[tex]d(x)=5x^2[/tex]
All the functions a through d are quadratics because they are polynomials with degree 2.
Also each one of them are comparable to the quadratic expression:
[tex]ax^2+bx+c[/tex].
Examples of exponential:
[tex]e(x)=5^x[/tex]
[tex]g(x)=5 \cdot 3^{3x}[/tex]
Notice all of these have a variable exponent on a constant base.
