3. The graph of part of linear function h is shown on the grid. (a) Write an inequality to represent the domain of the part shown. Explain your answer.
(b) Write an inequality to represent the range of the part shown. Explain your answer.

a). (4, ∞)

b). (-∞, -2)

Step-by-step explanation:

Graph attached shows the part of a linear function 'h'.

a). A hollow point at x = 4 shows that the function is not defined at x = 4

   Function 'h' is defined for all x- values greater than 4.

    Domain of the linear function → x > 4 Or (4, ∞)

b). Since, the given function has output values (y-values) for every x > 4

    Range of the linear function → y < -2 Or (-∞, -2)

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
