F(-3) = 8
Plug -3 into x and just solve it.
Answer:
just sub in the numbers into the equation to replace the X ..
example for
a) h(7) : 44
Step-by-step explanation:
h(7) : x^2 -5
sub in 7 into the equation to replace X
so you get
(7)^2 - 5
49-5
44
Use the slope formula and slope-intercept form Y=Mx+b to find the equation.
Y=2x + 14
The interval notation for numbers greater than 2 but less than or equal to 20 is (2,20]
