Answer:
-2
Step-by-step explanation:
3x isnt used because it stated when x>1.
so -2(1) is -2, because x =< 1 is true
Answer:
Nonlinear
Explanation:
y=2/3 x^2-7 is nonlinear because it is not in slope intercept form.
Also, x² automatically means it is nonlinear because this is the formula for a parabola when graphed. Parabolas are nonlinear.
The parabola also doesn't continue in a straight or nearly straight line. That is what linear is.
Answer:
y=5
Step-by-step explanation:
Use the given slope and point to substitute into the point-slope formula then you can solve for slope/intercept form
Tip: If the slope is 0 the equation is going to be y= the y of your original point (-2,5)
Answer:
f(1) = 2 f(3) = 8 f(t) = 2^t
Step-by-step explanation:
you just plug in the number in the parenthesis next to f to x in the equation 2^x
